Applications

General

The Digitrip 3000 microprocessor-based relay provides reliable 3-phaseand ground overcurrent protection forall voltage levels. It can be used forany application where instantaneousand/or time overcurrent protection isrequired. It is most commonly used asprimary feeder circuit protection, as inFigure 4.1-1.

Figure 4.1-1. Primary Feeder Protection

The Digitrip 3000 may be applied asthe transformer primary protection oras backup to the differential protec-tion, as in Figure 4.1-2.

Figure 4.1-2. Transformer Protection

The Digitrip 3000 may be connectedto the secondary side of a Delta-wyegrounded transformer with the groundelement connected to a separate CTin the neutral connection of the trans-former. With this connection, a lowerCT ratio and a pickup setting can beused to provide more sensitiveground fault protection especiallyfor resistance grounded systems(see Figure 4.1-3).

Figure 4.1-3. Transformer SecondaryProtection with Ground CT Connection

The Digitrip 3000 relay has specialprovisions for connection in a Zone Interlocking Scheme which can beused for bus protection or to improveprotection coordination in a tight orclose system. Zone interlocking isdescribed in more detail on Page 4.1-4.

Time Overcurrent Reset

The Digitrip 3000 includes time delay

reset characteristic for the time over-current functions. This improves theovercurrent protection response toarcing fault conditions. The currentduring an arcing fault may vary aboveand below the pickup level. The timeabove pickup will accumulate untiltrip occurs.

Overcurrent Protection

The Digitrip 3000 provides complete3-phase and ground protection withseparate elements and settings. Therelay can be used with CT ratios from5/5 to 5000/5. The CT ratio can be set

independently for phase and groundallowing the ground element to beconnected in either the residual or theseparate ground CT configuration, asin Figure 4.1-4 and Figure 4.1-5.

ApplicationsThe phase and ground overcurrentcharacteristics are defined by sixparameters.

ቢ Curve shape.

ባ Overcurrent pickup.

ቤ Time multiplier or dial.

ብ Short delay pickup.

ቦ Short delay time.

ቧ Instantaneous pickup.

Figure 4.1-6. Phase or Ground OvercurrentCharacteristics

Phase Curve Shape

The Digitrip 3000 includes the thermal,ANSI and IEC family of curves whichmake it easy to coordinate with anyconventional protection scheme. Theuser can select Moderately Inverse,

Very Inverse, Extremely Inverse orDefinite Time characteristics. TheThermal curves It, I2t, I4t and FlatSlopes can also be selected.

Phase Time Overcurrent Protection

Time overcurrent (overload and fault)protection is defined by the currentpickup setting and time multiplier.

Phase Short Time Protection

Short time (fault) protection respondsto short circuit conditions. It is similarto the Phase Long Time Protection inthat current and time settings areoffered. It differs, however, in twoways: (1) “NONE” is a Short DelayPickup setting which, if selected,will disable the Phase Short TimeProtection, and (2) a slope selectionis not available for the time line.

Instantaneous Protection

Instantaneous (short circuit) protectionreacts to high level fault currents.If “NONE” is selected for the instanta-neous setting, the instantaneous tripfunction is disabled and a true making

current release (discriminator)function is provided. If selected,the discriminator is functional for10 cycles and will trip the breakerinstantaneously, if the fault currentis above 11 times (In).

Ground Fault Protection

The ground fault protection functionis a composite of the ground:

Ground curve shape.

Time overcurrent and pickuptime settings.

Short delay current and timesettings.

Instantaneous setting.

A “NONE” setting selection disablesthat characteristic of the ground faultprotection.

Feeder Protection


Figure 4.1-8. Sample Zone Selective Interlocking System

Zone Selective Interlocking(Phase and Ground)

Zone Selective Interlocking is a protec-tion function to minimize equipmentdamage resulting from a phase fault ora ground fault in an area where longtime and/or short time delay is in use.

When the “Ground Zone Interlocking”feature is utilized, an immediate tripis initiated when the fault is in the

breaker’s zone of protection, and norestraining signal received regardlessof its preset time delay. When the“Phase Zone Interlocking” feature isutilized, the time overcurrent and shortdelay phase elements work as follows.The short delay phase element willinitiate an immediate trip when thefault is in the breaker’s zone of protec-tion, and no restraining signal receivedregardless of its preset time delay. Thetime overcurrent phase element willinitiate an immediate trip when thefault is in the breaker’s zone of protec-tion, and no restraining signal receivedregardless of its preset time delay onlywhen the current being sensed by theDigitrip 3000 exceeds 300% (3 x In) of the current transformer rating.

Upstream Digitrip 3000 protectedbreakers are restrained from trippingimmediately by an interlocking signalfrom the downstream Digitrip 3000relay. This interlocking signal requiresonly a pair of wires from the down-stream breaker to the upstream breaker.It provides standard coordinated trip-ping when the fault is located outsidethe zone of protection.

In the sample zone interlocking system

shown above, circuit breakers A, B andC are equipped with Digitrip 3000overcurrent relays.

Fault Location Zone 3

Note: For the phase time overcurrentelement, the current sensed by the Digitrip3000 must exceed 300% (3 x In) for the zoneselective interlocking to initiate an immedi-ate trip signal.

If a fault occurs at a point in Zone 3, theDigitrip 3000 of Downstream Breaker Csenses the fault and sends a restrain-ing signal to the upstream Digitrip3000 of Feeder Breaker B. Havingreceived this signal, the Digitrip 3000of Feeder Breaker B withholds itstrip command. As a result, onlyDownstream Breaker C is tripped.



If a fault occurs at a point in Zone 2,the Digitrip 3000 of Feeder Breaker Bsenses the fault and sends a restrainingsignal to the upstream Digitrip 3000 of Main Breaker A.

The Digitrip 3000 of the DownstreamBreaker C does not see this fault sinceit is situated on the downstream sideof the fault. As a result, the Digitrip3000 of Downstream Breaker C doesnot send a restraining signal to the

Digitrip 3000 of Feeder Breaker B.

Since it did not receive a restrainingsignal from the Digitrip 3000 of Downstream Breaker C, the Digitrip3000 of Feeder Breaker B identifies thatthe fault is in Zone 2 and immediatelytrips Feeder Breaker B, regardless of its time setting.



If a fault occurs in Zone 1, no restrain-ing signal is received by the Digitripof Main Breaker A. As a result, MainBreaker A is immediately tripped by itsDigitrip overcurrent relay, regardlessof its time setting.

Digitrip 3000 Relay with Dual-Source Power Supply

Digitrip 3000 with Dual-Source Power Supply

General DescriptionEaton’s Cutler-Hammer Digitrip 3000with Dual-Source Power Supply(DSPS) is a microprocessor-basedfeeder overcurrent protective relaydesigned for ac auxiliary power appli-cations. The DSPS versions, Digitrip3010 and Digitrip 3020, include anintegral power supply module which:

Powers the relay from nominal120 Vac, 50/60 Hz (Digitrip 3010model) or 240 Vac, 50/60 Hz(Digitrip 3020 model) auxiliarypower, which is normally connectedand available.

Operates solely from the maincurrent transformers (CTs) duringa fault if the normally connectedauxiliary ac voltage is not available,like an electromechanical relay or anelectronic “self-powered” relay.

The transition from externalauxiliary ac power to current poweris smooth with no time delay.

The CT powering capability is criticalfor tripping if the ac auxiliary supply orits fuses fail prior to the fault; or if thefault itself collapses, the supply volt-age at the critical moment when trip-ping is needed.

The Digitrip 3000 with Dual-SourcePower Supply design offers significantperformance and reliability benefitsover the electromechanical or “self-powered” relays. It provides a full-timemetering display, remote communica-tions, and self-monitoring functions.In addition, there is no calibrationrequired. The burden is lower thanmost electromechanical and solid-stateself-powered relays.

The Digitrip 3000 with DSPS provideslong-term, robust, maintenance-freeperformance, which can’t be achievedwith an energy-storing uninterruptiblepower supply (UPS). The DSPS willoperate anytime there is a fault evenafter an extended power outage.

Functional Description

The Dual-Source Power Supplycontains one ac voltage transformerand three ac current transformers. Theac voltage transformer is used to sup-ply nominal ac control power to theunit. The current transformers areused to power the unit from the linecurrent. Normally, the unit will operatefrom the ac auxiliary power. Since thisvoltage is usually obtained from thesystem containing the circuit that therelay is protecting, a fault on theprotected line could cause the acvoltage to drop below an acceptableoperating level. Below approximately70 volts for Digitrip 3010 or 140 voltsfor Digitrip 3020, the DSPS switchesover to current powering. All three cur-rent transformer secondaries are con-nected in series to supply this power.The DSPS will supply enough powerto operate the Digitrip 3000 over-current relay in the tripped state withcurrents greater than 1.8 per unit ratedsecondary current, or 9 A, in a single-phase. The DSPS will operate with3-phase currents in a tripped state withcurrents greater than 1.2 per unit or 6 Arated secondary current.

Note: There will be no effect to the Digitrip3000 relay trip time accuracy when theDual-Source Power Supply switches fromnormal ac voltage to fault-current power.

Burden Data

In normal operating conditions, theburden is <0.08 ohms at 1 ampere with3-phase current, or 0.2 per unit, anddrops to less than 0.04 ohms at highcurrent levels. Figure 4.1-11 and Figure

4.1-12 present CT burden data in ohmsand volt-amperes. In these cases, theburden shown is the total CT terminalvalue, which is the DSPS plus the relaymeasuring circuits, for the indicatedoperating condition.

Figure 4.1-11 shows burden imped-ance magnitude in ohms. The twolower curves are the values with acpower applied; the upper two are withCT powering only. For each of thesepairs, one curve shows the burden fora single-phase current (representing asingle-phase-to-ground fault) and theother for three balanced phases withnormally arrayed 120-degree phase

angle increments. There is no phasesequence sensitivity.

Figure 4.1-12 shows the burden involt-amperes for the same four cases.

The 3-phase burden cases assumethe normal angular distribution of the phases at 120-degree intervals.If the 3-phase current inputs areconnected in series to a single currentsource for a lab-bench test, burdenresults will be slightly different.

Digitrip 3000 — Drawout Case Option

General DescriptionThe quick-release Drawout Case option permits easyremoval and replacement of the protective unit withoutdisruption of the wiring. The CT circuits are self-shortingwith make-before-break operation on removal. All voltageinputs, discrete inputs and contact outputs are disconnectedwhile maintaining security against false tripping.

The terminal blocks feature a 2-stage disconnect operation.Removal of the Eaton’s Cutler-Hammer Digitrip 3000 InnerChassis will disconnect the trip circuits and short the CTsecondaries before the unit control power is disconnected.Upon insertion of the Inner Chassis, the control powerconnections are made before the trip circuits are activated.This feature provides added security against false tripping.

FP-4000Feeder Protection Relay

FP-4000 Relay

General DescriptionEaton’s Cutler-Hammer FP-4000 feederprotection relay is a multi-functional,microprocessor-based relay for feedercircuits of all voltage levels. It maybe used as primary protection formain, feeder and tie circuit breakerapplications, transformers and asbackup protection for high voltagelines and differential protection.

The FP-4000 feeder protection relay

provides complete current and voltageprotection and metering. The relayhas four current inputs rated for either5 amperes or 1 ampere and four volt-age inputs. Three of the voltage inputsare to be connected to the 3-phasepower voltage for voltage protectionand for metering. They can be con-nected in wye-ground, delta or opendelta configuration. The fourth voltageis for independent single-phaseundervoltage/overvoltage protection.

The multiple settings groups can beutilized for arc flash mitigation whenan alternate settings group, set tohave instantaneous elements only, is

activated using a selector switch andthe programmable I/O in the FP-4000.

An integral keypad and display isprovided for direct user programmingand retrieval of data. LEDs providequick indication of relay status.A front port is provided for directcomputer connection. An INCOMcommunication port on the back of the relay is standard for local areanetworking. Optional communicationports and protocols are available.

The FP-4000 feeder protection relayincludes programmable logic func-tions. Six gates and timers may bedefined and arranged for customizedapplications. Flash memory is used forthe programming and all settings arestored in nonvolatile memory. Therelay allows for four preprogrammedsetting groups which can be activatedthrough software or contact input.

The FP-4000 feeder protection relayhas mass memory for data storageand a real-time clock with 1 ms timeresolution. The relay will log 100sequence of event records, detailedtrip logs, minimum/maximum values,load profiles, breaker wear informationand oscillography data.

The FP-4000 feeder protection relayhas eight programmable binary inputs,five normally opened heavy duty

outputs and one form C signal relay.Features

Protection FunctionsThe Eaton’s Cutler-Hammer FP-4000feeder protection relay has beendesigned for maximum user flexibilityand simplicity. The base relay includes

all the standard current and voltageprotection and metering functions.

Overcurrent Protection

The FP-4000 feeder protection relayprovides complete 3-phase and groundovercurrent protection. There aretwo independent ground overcurrentelements. The first ground element “X”uses the independently measured ground(or neutral) current from a separatecurrent-sensing input. The second groundelement “R” uses a calculated 3Io currentobtained from the sum of the 3-phasecurrents. This calculated current couldbe used for either the neutral or groundcurrent in a 3-phase, 4-wire system.

Each of the phase and ground over-current elements provides three protec-tion functions. Each element containsan inverse-time overcurrent (51) func-tion and two instantaneous overcurrent(50) functions with adjustable timers.

Inverse-Time Characteristics

There are 10 user-selectable inverse-time overcurrent curve characteristics.The user can select from the ANSI,IEC or thermal curve families andcan select instantaneous or time delayreset characteristics.

Breaker Failure

The FP-4000 feeder protection relayincludes a breaker failure (50BF, 62BF)function that can be initiated fromeither an internal or external trip signal.This is an independent element thatcan be used to operate a lockout relayor trip an upstream breaker. The timermust be longer than the breaker operat-ing time and the protective functionreset times.

Voltage Protection

The FP-4000 feeder protection relayhas four voltage-input circuits. Thereis a 3-phase set designated as MainVoltage (M) and a single-phase voltagecircuit designated as Auxiliary Voltage

(A). Both include undervoltage (27)and overvoltage (59) protection.The 3-phase voltage protection canbe set to operate on a single-phase,2 out of 3 phases, or all 3-phase logic.The Main VTs also provide phase volt-age unbalance/reversal (47 negativesequence) protection. Each elementhas an independent threshold setpoint and adjustable time delay.

Flexible Phase Rotation

The FP-4000 feeder protection relaycan be applied on either an A-B-C orA-C-B phase rotation. A user settingpermits correct operation and indica-tion of the actual system configuration.

Frequency Protection

The FP-4000 relay provides under/overfrequency (81U/81O) protection on theMain VT inputs. Each element has anindependent threshold set point andadjustable time delay.

Metering

The FP-4000 feeder protection relay pro-vides complete and accurate metering of the voltages, currents, frequency, power,power factor and energy. Informationis available on the individual phase

magnitude, angles and the symmetricalcomponent values of positive, negativeand zero sequence current and voltage.

The FP-4000 feeder protection relayincludes a programmable demand fea-ture and stores the maximum demand of current, kW, kvar and kVA since last reset.The demand is user-configurable forfixed or sliding window, the time intervalis adjustable and the demand intervalcan be synchronized to a demand pulse.

Energy usage direction and net valuesare given for kWh, kvarh and kVAh.The relay monitors, logs and timestamps minimum and maximum

values for current, voltage, watts,vars, VA, power factor and frequency.

The FP-4000 feeder protection relayhas metered set points that can beused to activate an output for analarm, control or trip function.For example, you might want to closea contact to insert a capacitor bankif the power factor is less than 0.9lagging or provide an alarm if thedemand is greater than a preset value.

Loading Profile

The FP-4000 feeder protectionrelay has memory available to storemetered data on a predeterminedinterval. The log holds data from1024 time sample intervals. This

information can be retrieved andplotted with a PC to show the loadingprofile of a given circuit over a periodof time. For example, if the timeinterval is set for 15 minutes, then therelay will store a metered data profileover an approximate 10-day period.

Sequence of Events Records

The FP-4000 feeder protection relayrecords a maximum of 100 eventsassociated with the relay. An eventis classified as a change of state asdetected by the relay. These includerelay pickups, dropouts, trips, contactclosure, alarms, setting changes and

self-diagnostic failures. Each eventis date and time stamped to a 1 msresolution. The events are stored ina FIFO in chronological order.

Trip Log

The FP-4000 feeder protection relay willstore a maximum of 16 trip records ina FIFO trip log. Each trip record willbe date and time stamped to a 1 msresolution and reference an event num-

ber associated with oscillographic andsequence of event data. The trip logrecord will include information on thetype of fault, protection elements thatoperated, fault location and currentsand voltages at the time of the fault.

Waveform Capture

The FP-4000 feeder protection relayprovides oscillography-recordingcapabilities. The relay will record allvoltage and current signals along withthe binary signals of pickup, trip, logicand contact closures. The FP-4000relay can record 16 records of 16cycles of data. Fewer records of longer

duration can be selected and recorded.The waveform capture is initiated bya trip, pickup, external contact, frontpanel interface or through the remotecommunications port.

Programmable Logic

The FP-4000 feeder protection relayprovides six logic gates and timersthat the user can customize for specialor unique applications. Each gate canbe assigned a logic function of either

AND, OR, NAND or NOR. Each gatecan have a maximum of four inputsignals and each input signal can berequired to be a NOT. Input signalscan be external inputs received viathe binary inputs or internal valuesassociated with the protection, alarmor metering set points. Each gatehas a unique output assignmentand designation that can be usedas the input to another gate. Thereare six independent timers thathave adjustable pickup and dropoutdelay settings.

Integral User Interface

The front panel user interface has a

4 x 20-inch (101.6 x 508.0 mm) alpha-numeric vacuum fluorescent displayfor wide angle viewing in all lightconditions. LEDs provide quick andeasy visual display of power on, modeof operation, alarm and trip indication.Pushbuttons are provided for opera-tion mode selection, scrolling throughdata and settings. A security doorrestricts access to the program andtest modes. In addition, the relaysettings and test functions can bepassword protected.

Programmable I/O

The FP-4000 feeder protection relayprovides five heavy-duty, trip-rated,normally open contacts and two FormC auxiliary contacts. Two trip ratedcontacts are fitted with a circuitcontinuity feature for monitoring thetrip or close circuits. One Form Ccontact is dedicated to the relay failurealarm function and is operated in anormally energized (failsafe) mode.There are eight user-configurablediscrete inputs that accept a drycontact. Each input and output is

user-programmable for maximumapplication flexibility.

Communication SoftwareEaton provides two types of communi-cation software. The first is PowerPort.It runs on a PC or laptop for easy accessto a single relay to change set points orconfiguration and to view metered val-ues and stored data. PowerPort is freeand can be downloaded from the EatonWeb site at the following URL:http://www.EatonElectrical.com

The second package is PowerNet.PowerNet is a power managementsoftware package that is designed for

continuous, remote monitoring of many devices. It provides all the func-tionality of PowerPort plus additionalfunctions such as billing, trending andgraphics. Contact your local Eatonrepresentative for more informationon PowerNet software.

Transview

Transview is a Comtrade file viewerthat is required in addition to thePowerNet waveform client to viewFP-4000 waveforms. Users can viewindividual voltage and current wave-forms, as well as phasers and digitalinput/output and internal protectionfunctions such as undervoltage andcurrent unbalance.

Protection FunctionsThe Eaton’s Cutler-Hammer FP-5000feeder protection relay has beendesigned for maximum user flexibilityand simplicity. The base relay includes

all the standard current and voltageprotection and metering functions.

Directional Overcurrent Protection

The FP-5000 feeder protection relayprovides complete 3-phase and grounddirectional overcurrent protection. Thereare two independent ground overcurrentelements. The first ground element “X”uses the independently measured ground(or neutral) current from a separatecurrent-sensing input. The second groundelement “R” uses a calculated 3Io currentobtained from the sum of the 3-phasecurrents. This calculated current couldbe used for either the neutral or groundcurrent in a 3-phase, 4-wire system.

Each of the phase and ground over-current elements provides three protec-tion functions. Each element containsan inverse-time overcurrent (51) func-tion and two instantaneous overcurrent(50) functions with adjustable timers.

Phase direction is a function used tosupervise all phase current elements(50, 51). A quadrature voltage is com-pared to a corresponding phase currentto establish the direction of the fault.This function is selectable to operate inthe forward, reverse or both directions.

Ground direction is used to supervise

ground current elements and is accom-plished by using ground, negativesequence or residual currents super-vised by zero or positive sequencevoltages or ground current. This func-tion is selectable to operate in forward,reverse or both directions.

Voltage Restrained Overcurrent

Voltage restraint reduces the overcur-rent pickup level (51P-2). This modifi-cation of the pickup overcurrent levelis compared to the correspondingphase input voltage. The FP-5000 uses

the simple linear model below todetermine the effective pickup value.

Figure 4.1-20. Voltage Restraint Coil PickupCharacteristics

Sync CheckThe sync check function is providedfor double-ended power sourceapplications. The sync check monitorsvoltage magnitude, phase angle andslip frequency between the bus andline. It also incorporates breaker closetime, dead bus dead line, dead bus liveline and live bus live line features.

Reverse Power

Reverse power provides control forpower flowing through a feeder. Thereare two elements to be configured:operate in forward or reverse; or,under or over power conditions.Reverse power is typically applied togenerator or motor applications whileunder power is generally applied toload or generation loss.

Inverse-Time Characteristics

There are 10 user-selectable inverse-time overcurrent curve characteristics.The user can select from the ANSI,IEC or thermal curve families andcan select instantaneous or time delayreset characteristics.

Breaker Failure

The FP-5000 feeder protection relayincludes a breaker failure (50BF, 62BF)

function that can be initiated fromeither an internal or external trip signal.This is an independent element thatcan be used to operate a lockout relayor trip an upstream breaker. The timermust be longer than the breaker operat-ing time and the protective functionreset times.

Voltage Protection

The FP-5000 feeder protection relayhas four voltage-input circuits. Thereis a 3-phase set designated as MainVoltage (M) and a single-phase voltagecircuit designated as Auxiliary Voltage

(A). Both include undervoltage (27)and overvoltage (59) protection. The3-phase voltage protection can be setto operate on a single-phase, 2 out of 3 phases, or all 3-phase logic. The MainVTs also provide phase voltage unbal-ance/reversal (47 negative sequence)protection. Each element has an inde-pendent threshold set point andadjustable time delay.

Flexible Phase Rotation

The FP-5000 feeder protection relaycan be applied on either an A-B-C orA-C-B phase rotation. A user settingpermits correct operation and indica-tion of the actual system configuration.


The FP-5000 relay provides under/overfrequency (81U/81O) protection on theMain VT inputs. Each element has anindependent threshold set point andadjustable time delay.

Metering

The FP-5000 feeder protection relayprovides complete and accurate meter-ing of the voltages, currents, frequency,power, power factor and energy. Infor-mation is available on the individualphase magnitude, angles and thesymmetrical component values of

positive, negative and zero sequencecurrent and voltage.

The FP-5000 feeder protection relayincludes a programmable demandfeature and stores the maximumdemand of current, kW, kvar and kVAsince last reset. The demand is user-configurable for fixed or slidingwindow, the time interval is adjustableand the demand interval can besynchronized to a demand pulse.

Energy usage direction and net valuesare given for kWh, kvarh and kVAh.The relay monitors, logs and timestamps minimum and maximum

values for current, voltage, watts,vars, VA, power factor and frequency.

The FP-5000 feeder protection relay hasmetered set points that can be used toactivate an output for an alarm, controlor trip function. For example, you mightwant to close a contact to insert a capac-itor bank if the power factor is less than0.9 lagging or provide an alarm if thedemand is greater than a preset value.

Loading Profile

The FP-5000 feeder protectionrelay has memory available to storemetered data on a predeterminedinterval. The log holds data from1024 time sample intervals. This

information can be retrieved andplotted with a PC to show the loadingprofile of a given circuit over a periodof time. For example, if the timeinterval is set for 15 minutes, then therelay will store a metered data profileover an approximate 10-day period.

Sequence of Events Records

The FP-5000 feeder protection relayrecords a maximum of 100 eventsassociated with the relay. An eventis classified as a change of state asdetected by the relay. These includerelay pickups, dropouts, trips, contactclosure, alarms, setting changes and

self-diagnostic failures. Each eventis date and time stamped to a 1 msresolution. The events are stored ina FIFO in chronological order.

Trip Log

The FP-5000 feeder protection relay willstore a maximum of 16 trip records ina FIFO trip log. Each trip record willbe date and time stamped to a 1 msresolution and reference an event num-ber associated with oscillographic andsequence of event data. The trip logrecord will include information on thetype of fault, protection elements thatoperated, fault location and currentsand voltages at the time of the fault.

Waveform Capture

The FP-5000 feeder protection relayprovides oscillography-recordingcapabilities. The relay will record allvoltage and current signals along withthe binary signals of pickup, trip, logicand contact closures. The FP-5000relay can record 16 records of 16cycles of data. Fewer records of longerduration can be selected and recorded.The waveform capture is initiated bya trip, pickup, external contact, frontpanel interface or through the remotecommunications port.

Programmable Logic

The FP-5000 feeder protection relayprovides six logic gates and timersthat the user can customize for specialor unique applications. Each gate canbe assigned a logic function of either

AND, OR, NAND or NOR. Each gatecan have a maximum of four inputsignals and each input signal can berequired to be a NOT. Input signalscan be external inputs received viathe binary inputs or internal valuesassociated with the protection, alarmor metering set points. Each gatehas a unique output assignmentand designation that can be usedas the input to another gate. Thereare six independent timers thathave adjustable pickup and dropoutdelay settings.

Integral User Interface

The front panel user interface has a4 x 20-inch (101.6 x 508.0 mm) alpha-numeric vacuum fluorescent displayfor wide angle viewing in all lightconditions. LEDs provide quick and

easy visual display of power on, modeof operation, alarm and trip indication.Pushbuttons are provided for opera-tion mode selection, scrolling throughdata and settings. A security doorrestricts access to the program andtest modes. In addition, the relaysettings and test functions can bepassword protected.

MP-3000Motor Protection Relay

MP-3000 Motor Protection Relay

General DescriptionEaton’s Cutler-Hammer MP-3000 motorprotection relay is a multi-functionalmicroprocessor-based protective relayfor the protection of any size motor atall voltage levels. It is most commonlyapplied on medium voltage startersand on critical or larger motors. TheMP-3000 relay is a current only devicethat provides complete and reliablemotor protection, monitoring andstarting control functions.

The MP-3000 motor protection relayis available in either a fixed mount,semi-flush case or in a semi-flush quick-release drawout case. Both housingsare compact and fit a standard IQ cutout.

The optional quick-release drawoutcase features two-stage contact discon-nection and self-shorting CT circuitterminals. A spare self-shorting termi-nal pair is available for use as relayremoval alarm or for continuous motoroperation (non-failsafe mode) on relayremoval. The optional communicationmodule is externally mounted onthe fixed mount case and internally

mounted in the drawout case.The MP-3000 motor protection relayhas three phase and one ground currentinputs. Both a 5 ampere and 1 ampereversion are available. The ground pro-tection and metering functions can beused with either a zero sequence groundCT or from the residual connection of the phase CTs. The zero sequenceground CT provides greater ground faultsensitivity than the residual connection.The relay is programmable for 60 Hzor 50 Hz operation.

The MP-3000 motor protection relayhas two discrete inputs, four Form C(1NO and 1NC) contacts and one4 to 20 mA analog output. The relayprovides maximum user flexibility toconfigure the I/O. All inputs and out-puts (except for the trip output) areuser-programmable. In addition, therelay has 10 LEDs for the indication of protection on, program mode, monitormode, view setting mode, historymode, log mode, trip, alarm, auxiliary1 and auxiliary 2 operation. A test pagein the program mode provides displayindication of the discrete input statesand testing of the output relays, targetLEDs and analog circuit.

A user-friendly operator interface anddisplay provides quick access to thesettings, monitored values, motorhistory and operational logs. LargeLED alphanumeric character display

provides easy viewing from any anglein any light. Simple keypad operationprovides quick and easy navigationthrough all settings and stored data.The program mode and emergencyoverride buttons are access restrictedvia a latched cover which can be sealedif required. An integrated help functionprovides an online description display of functions, abbreviations and operations.

Optimum Motor Protection

The MP-3000 motor protection relayhas been designed for maximummotor operation and protection. Itpermits running the motor as close

to its design limits while protecting itagainst excessive heating and damag-ing overload conditions. The MP-3000field proven protection algorithmswere developed based on motordesigns and operating parametersfor optimum operation and protectionwhile minimizing nuisance tripping.

The MP-3000 motor protection relayutilizes a patented protection algorithm

and measurement technique based onproven positive and negative (unbal-ance) sequence current sampling andtrue rms calculations.

JAM Protection

The user-selectable JAM function pro-tects motors that are running against asudden mechanical jam or stall condi-tion. The common application is onmotors used on crushers, chippers or

conveyors. It detects an increase of motor current to a level above fullload. Pickup, start and run timers anda separate alarm setting are provided.

Figure 4.2-1. MP-3000Motor Protection Relay Functions

Underload Protection

The user-selectable underload func-tion is used to detect the loss of loadon the motor. Coupling failure is acommon cause for loss of load.Pickup, start and run timers and aseparate alarm setting are provided.

Reduced Voltage StartingEaton’s Cutler-Hammer MP-3000 motorprotection relay provides a transitionand incomplete sequence function forreduced voltage starting. The user canselect to transition based on the currentlevel or on time.

Anti-backspin

For certain applications, for example,pumping fluid up a pipe, the motormay be driven backward for a periodof time after it stops. The MP-3000relay provides an anti-backspin timer

to prevent starting the motor while itis spinning in the reverse direction.The timer begins counting from themoment a stop is declared by the relay.

Start Control Timers

Motors typically have limits to thenumber of cold starts, hot starts, startsper time period and time betweenstarts that are permitted withoutdamage. The MP-3000 motor protec-tion relay incorporates these timersto prevent starting the motor beyondits capabilities.

Load Shedding

The MP-3000 motor protection relayprovides a mechanical load sheddingfeature that can be used to control anupstream process. The load sheddingfunction closes a contact on an over-load condition to control an upstreamprocess from adding more load untilthe overload condition is gone.

Emergency Override

The MP-3000 motor protection relayhas a user-programmable feature thatwill let the operator reset the startcontrol timers and thermal overloadbucket. This function is intended foruse in emergency conditions only andmay result in motor damage or failure.

Long Acceleration Motors

Large motors with high inertia loadsmay experience starting currents thatexceed the locked rotor current andtime. The MP-3000 motor protectionrelay has logic and provisions for a

zero speed switch input to differentiatebetween a stall and start condition. If the motor is spinning then the relaywill not trip on the normal locked rotortime allowing the motor to start.

Remote/Differential Trip

One of the binary inputs can be pro-grammed to accept a contact inputfrom a separate differential relay, suchas the MD-3000 or other device to tripthe motor. This provides local andremote target information and utilizesthe trip contacts of the MP-3000 motorprotection relay. It will also record andlog the motor information at the time

of the trip.

Motor Starting Profile Time/Current Chart

Motor Starting ProfileThe MP-3000 relay records the averagecurrent of the motor for the last twostarts. This information is availableover the communications port. Themotor current can then be plotted andcompared to the motor overload pro-tection curve. Available in PowerPort orthe PowerNet Event Viewer Client.

MP-4000 Motor ProtectionRelay with Voltage Inputs

MP-4000 Motor Protection Relay

General DescriptionEaton’s Cutler-Hammer MP-4000 motorprotection relay is a multi-functionalmicroprocessor-based protective relayfor the protection of any size motor atall voltage levels. It is most commonlyapplied on medium voltage startersand on critical or larger motors. TheMP-4000 relay provides complete andreliable motor protection, monitoringand starting control functions.

The MP-4000 motor protection relayis available in either a fixed mount,semi-flush case or in a semi-flushquick-release drawout case.

The optional quick-release drawoutcase features two-stage contact discon-nection and self-shorting CT circuitterminals. A spare self-shorting termi-nal pair is available for use as relayremoval alarm or for continuous motoroperation (non-failsafe mode) on relayremoval. The optional communicationmodule is externally mounted onthe fixed mount case and internallymounted in the drawout case.

The MP-4000 motor protection relayhas three phase and one ground currentinputs. The MP-4000 also has three volt-

age inputs. Both a 5 ampere and 1 ampereversion are available. The ground protec-tion and metering functions can be usedwith either a zero sequence ground CT orfrom the residual connection of the phaseCTs. The zero sequence ground CT pro-vides greater ground fault sensitivity thanthe residual connection. The relay is pro-grammable for 60 Hz or 50 Hz operation.

The MP-4000 motor protection relayhas two discrete inputs, four Form C(1NO and 1NC) contacts and one 4 to 20mA analog output. The relay provides

maximum user flexibility to configurethe I/O. All inputs and outputs (exceptfor the trip output) are user-program-mable. In addition, the relay has 10LEDs for the indication of protectionon, program mode, monitor mode,view setting mode, history mode,og mode, trip, alarm, auxiliary 1 andauxiliary 2 operation. A test page inthe program mode provides displayindication of the discrete input statesand testing of the output relays,target LEDs and analog circuit.

A user-friendly operator interface anddisplay provides quick access to thesettings, monitored values, motorhistory and operational logs. LargeLED alphanumeric character displayprovides easy viewing from any anglein any light. Simple keypad operationprovides quick and easy navigationthrough all settings and stored data.The program mode and emergencyoverride buttons are access restrictedvia a latched cover which can be sealedif required. An integrated help functionprovides an online description display of functions, abbreviations and operations.

Optimum Motor Protection

The MP-4000 motor protection relayhas been designed for maximummotor operation and protection. Itpermits running the motor as closeto its design limits while protecting itagainst excessive heating and damag-ing overload conditions. The MP-4000field proven protection algorithmswere developed based on motor

designs and operating parametersfor optimum operation and protectionwhile minimizing nuisance tripping.

The MP-4000 motor protection relay uti-lizes a patented protection algorithmand measurement technique based onproven positive and negative (unbal-ance) sequence current sampling andtrue rms calculations.

User Interface

The MP-4000 motor protection relayhas a user-friendly interface thatmakes it easy to retrieve importantinformation or make setting changes.LEDs provide visual indication of

display and keypad mode. The push-buttons are clearly labeled and quicklyaccess the desired information.


The MP-4000 motor protection relayprovides protection against motoroverloads, short circuits and abnormaloperating conditions.

I2 t Overload

Motor overloads are typically limitedby the rotor thermal capabilities butthe measuring quantities are fromthe stator. This requires accurate mea-surements and good motor thermalmodels to provide reliable protection.

The MP-4000 motor protection relayutilizes a field proven measurementand motor thermal protection model.The relay samples the current wave-forms 36 times per cycle providingaccurate measurements of the positiveand negative sequence currents. Thenegative sequence component of current causes greater heating effecton the rotor and has a greater impacton the thermal model in the relay.This same algorithm has been usedto protect thousands of motorssince 1984.

The MP-4000 motor protection relayoverload protection is easy to set andapply. Simply input motor nameplateinformation and CT ratios and thecharacteristic is automatically set.

When utilizing the MP-4000 motorprotection relay, it is recommendedthat the ratio of CT primary rating tothe motor full load amperes (CT Pri/ Motor FLA) is selected to fall between0.25 and 1.5. The thermal modeladapts its tripping characteristics if RTDs are connected.

Instantaneous Overcurrent

The MP-4000 motor protection relay

provides an instantaneous phase over-current function to trip the motor forhigh fault current levels. This functioncan be disabled and has an adjustabletime delay on starting to avoidnuisance tripping on inrush.

Motor Protection


Current Unbalance Protection

Motor supply circuits are often fedthrough fuses and can be run with asingle-phase fuse blown. The motormay still see 3-phase voltage but willonly have current on two phases,

referred to as single-phasing themotor. The MP-4000 motor protectionrelay measures the current unbalanceand can be used to alarm or trip themotor before damage occurs. Pickup,start and run timers and a separatealarm setting are provided.

Voltage Unbalance Protection

The MP-4000 will calculate negativesequence voltage from three-phasevoltages. The presence of negativesequence voltage identifies either aphase unbalance or reverse phaserotation condition. The MP-4000 pro-vides both alarm and trip functionality.

Ground Fault ProtectionA separate circuit measures groundfault current. A ground CT is recom-mended for more sensitive protectionagainst winding fault ground. Therelay ground circuit can be connectedresidually from the 3-phase CTs. Theground fault protection has pickup andtime delay set points or can be disabled.


The MP-4000 provides over/underprotection on the Main VT inputs.Each element has an independentthreshold and time delay.

Voltage ProtectionThe MP-4000 voltage protection canbe used to generate a trip or alarm if the voltage exceeds (overvoltage 59)a specified threshold for a specifictime delay or drops below (undervolt-age 27) a specified threshold for aspecified time delay. Voltage elementscan act on one, two or three phases.

Power Factor

The power factor function in theMP-4000 can be used for manyapplications. For a synchronous motor,it can be used to indicate field loss.The power factor protection can

generate a trip or alarm whenthe power factor falls betweenspecified thresholds.

JAM Protection

The user-selectable JAM function pro-tects motors that are running againsta sudden mechanical jam or stallcondition. The common application ison motors used on crushers, chippers

or conveyors. It detects an increaseof motor current to a level above fullload. Pickup, start and run timers anda separate alarm setting are provided.

Underload Protection

The user-selectable underload func-tion is used to detect the loss of loadon the motor. Coupling failure is acommon cause for loss of load.Pickup, start and run timers and aseparate alarm setting are provided.

Reduced Voltage Starting

Eaton’s Cutler-Hammer MP-4000 motorprotection relay provides a transitionand incomplete sequence function forreduced voltage starting. The user canselect to transition based on the currentlevel or on time.

Anti-backspin

For certain applications, for example,pumping fluid up a pipe, the motormay be driven backward for a periodof time after it stops. The MP-4000relay provides an anti-backspin timerto prevent starting the motor while itis spinning in the reverse direction.The timer begins counting from themoment a stop is declared by the relay.

Start Control Timers

Motors typically have limits to thenumber of cold starts, hot starts, startsper time period and time betweenstarts that are permitted withoutdamage. The MP-4000 motor protec-tion relay incorporates these timersto prevent starting the motor beyondits capabilities.

Load Shedding

The MP-4000 motor protection relayprovides a mechanical load sheddingfeature that can be used to control anupstream process. The load sheddingfunction closes a contact on an over-load condition to control an upstream

process from adding more load untilthe overload condition is gone.

Emergency Override

The MP-4000 motor protection relayhas a user-programmable feature thatwill let the operator reset the startcontrol timers and thermal overloadbucket. This function is intended foruse in emergency conditions only andmay result in motor damage or failure.

Long Acceleration Motors

Large motors with high inertia loadsmay experience starting currents thatexceed the locked rotor current andtime. The MP-4000 motor protectionrelay has logic and provisions for a

zero speed switch input to differentiatebetween a stall and start condition. If the motor is spinning then the relaywill not trip on the normal locked rotortime allowing the motor to start.

Remote/Differential Trip

One of the binary inputs can be pro-grammed to accept a contact inputfrom a separate differential relay, suchas the MD-3000, or other device to tripthe motor. This provides local andremote target information and utilizesthe trip contacts of the MP-4000 motorprotection relay. It will also recordand log the motor information at the

time of the trip.

Motor Starting Profile Time/Current Chart

Motor Starting ProfileThe MP-4000 relay records the averagecurrent of the motor for the last twostarts. This information is availableover the communications port. Themotor current can then be plotted andcompared to the motor overload pro-tection curve. Available in PowerPort orthe PowerNet Event Viewer Client.

DP-300 Current DifferentialProtection Relay

DP-300

General Description

The DP-300 offers a three-phase current

differential protection for generators,motors and two winding transformers.

The current flowing in the individualconductors is measured by means of current transformers installed on bothsides of the protection zone. Thesetransformers form the limits of theprotection zone. By means of freelyconfigurable relays, the unit will indi-cate if any of the adjusted fault currentlimits have been exceeded. The unitcounts with a slope characteristic toprevent operation due to CT ratiomismatches, CT ratio errors, CTsaturation, and errors because of tapchanges.

For transformer applications, the unithas 2nd and 5th harmonic restraints toprevent misoperation in case of inrushcurrents caused for energization orover excitation of the transformer.When used in transformer applications,the DP-300 allows change to the phaseshift of the transformer, without havingto change the connection of the exter-nal CTs, via selecting the vector groupin the display. The different nominalcurrents of the high and low voltageside of the transformer, as well as thetransformer ratio, may be configured.Every measuring point may be set

separately. These features permit theDP-300 to be universal in its applications.

The DP-300 permits design simplifica-tion of the switchgear cabinet, facili-tates the commissioning, ensuresthe operation of the system, is userfriendly, and increases the availabilityof the system.

Protective & Predictive RelaysInsulGard Predictive Maintenance

General Description — InsulGardSheet 0285

Product Description

InsulGard

The InsulGard is a continuouspartial discharge monitor that can beapplied to a variety of medium voltageelectrical equipment rated 4 kV to 38kV. It is commonly applied to motors,generators, switchgear, bus duct,unit substations and cable systems.The InsulGard will monitor the qualityof insulation while the equipment isin service under normal operatingconditions. Through monitoring, itcan ascertain the relative condition of

insulation, the deterioration of which isthe leading cause of electrical failures.

The InsulGard system consists of sensors and a monitor. The monitorcan be used as a stand-alone unit, orit can be wired so that it can remotelyupload data to your system or to Eatondiagnostics personnel for analysis.While the sensors vary according toapplication, they are all designedto detect partial discharges — thefoundation of the InsulGard technol-ogy and one of the best predictorsof insulation breakdown.

The term “partial discharge” is acommon name for small electricaldischarges (arcs) that typically occurwithin or between insulation materials— usually across a void in the insula-tion. Partial discharge is also referredto as corona or surface tracking. Thevisible evidence of corona presentsitself as white, powdery residue, typi-cally found on the end windings of motors or generators. Surface-trackingdamage appears as tree-like, jaggedlines, typically found on switchgearand bus ducts. Surface trackingstems from a contaminated insulationsurface, often started by corona. Thesmall arcing activity on the surface of the insulation contributes to furtherburning, resulting in additional stresspoints that promote further deteriora-tion. Both corona and surface trackingare the primary causes of insulationbreakdown, which can lead to fulldischarges and electrical failures.It is important to note that traditionalmethods of detecting corona and sur-face-tracking damage require takingequipment off line. It also requiresdisassembling the equipment — acostly procedure. Moreover, coronaand surface tracking damage have tobe severe to be visible. The InsulGardsystem allows you to detect partial dis-charge while the electrical system isenergized. It does so by detecting andanalyzing the radio signal frequenciesemitted by the partial discharges.More specifically, the InsulGardfocuses on the 1 MHz to 20 MHzbandwidth range where the majorityof partial-discharge activity can bedetected. InsulGard allows predictiveanalysis and maintenance as opposedto preventive analysis and time-basedmaintenance.

The detection of partial discharge onequipment can indicate if a problemexists. Even more useful is informationthat can correlate the signal intensity(measured in milliwatts) associatedwith partial discharges to variousstates of insulation degradationon similar equipment. The EatonElectrical/Cutler-Hammer Predictive

Diagnostics Group has studied numer-ous cases of partial discharge onrotating equipment and switchgear.The knowledge base accumulated hasallowed Eaton to develop guidelinesand parameters to help one determinethe seriousness (failure-time windows)of the partial-discharge activity theequipment may be exhibiting. Becauseit is a continuous, on-line monitoringsystem, it is easy to monitorconditions over time.

Cutler-Hammer InsulGard by EatonCorporation is a stand-alone micropro-cessor-controlled continuous partialdischarge monitoring device for awide range of medium voltage powerequipment. It is designed to providean alarm based on PD characteristicsat an early stage of insulation degrada-tion. It measures partial dischargesfrom up to 15 different partialdischarge sensors and stores theinformation in internal memory;alarming users if any set points areexceeded. InsulGard can work withconstant 50/60 Hz frequency poweredequipment, as well as with variablefrequency applications.

Various PD sensor types can be used,depending on the application.

InsulGard has three auxiliary inputsfor PD data correlation to additional

parameters. One of the inputs isdesignated for temperature, wherethe other two are commonly used forload, voltage or humidity dependingupon the application. InsulGard hasseveral interfaces that allow for easyimplementation into any alarm orSCADA system:

Three C-form dry relay contactsprovide Yellow or Red alarm indica-tion, and the Device Status relayindicates any device malfunction.

4 –20 mA optically isolated outputcan be configured to representPartial Discharge Intensity (PDI)or maximum discharge magnitudeto any SCADA system.

RS-485 optically isolated interfacebased on Modbus RTU protocolallows for remote device configura-tion and data download. InsulGardcan be networked with an existingModbus, allowing for up to 231addressable devices.

Note: RS-232 is also available onspecial order.

Communication protocol includesModbus, proprietary binary and ASCIItext options allowing a softwareprogrammer to build InsulGard into

a high-level software program usingsimple text type commands. InsulGardis supplied with database softwarethat allows for automated communica-tion to a device or several devicesfor data acquisition and analysis.The software allows for either directnetwork or dialup connection to adevice by a regular telephone landlineor a cellular connection.

InsulGard has 15 signal inputs(Ch1 – Ch15) for partial dischargemeasurement and a noise inputdedicated for noise suppression(Ch16). All 16 inputs have identicalconditioning circuits (CC) providingsignal isolation, transient suppres-sion, and high-pass filtering of theinput signals. The frequency band of the InsulGard is from 1 MHz to 20 MHz.

InsulGard acquires PD data in the formof three dimensional phase-resolvedpulse height distribution (PRPHD) -PD pulse count as a function of pulsemagnitude and 60(50) Hz phase. It has24 (15 0 ) phase windows and a magni-tude dynamic range of about 70 dB,divided in 21 magnitude windows.

The data can be stored in the internaldevice memory in the form of three-dimensional PRPHD matrixes and/or

in the brief form of integral quantitiesderived from these matrixes. Eachrecord is accompanied by threeadditional correlation parameters.

Before each measurement, InsulGardperforms self-calibration and self-test.If any problem is detected, the statusrelay dry contacts will open and anappropriate message will appear onthe InsulGard display. Loss of powerwill be indicated in the same way byopening status relay contacts.

InsulGard measures signals from sig-nal inputs sequentially multiplexingthem to a single metering channel.

Each pulse from each sensor is vali-dated by the allowed pulse width.In the case of non-compliance,InsulGard will not count the pulse.

After each measurement, data from allactive signal channels will be com-pared to alarm thresholds. If any of theYellow threshold limits are exceeded,the Warning LED will be turned onand the Warning relay dry contactswill close. In the case of a Red levelachieved, InsulGard will trigger addi-tional measurement and, if confirmed,an Alarm LED will be turned on andthe Alarm relay dry contacts willclose. If Red alarm is detected, fullmeasurement data will be stored inthe memory.

PD measurements can be performedon a time schedule (up to 50 per day)or in specified time intervals (from1 minute to 23 hours 59 minutes).Four measurements per day arerecommended.

Between scheduled measurements,

the “High Alarm” feature is enabled.All signal sensors are connected to asummation unit and further to a sepa-rate “High Alarm” channel. InsulGardcontinuously searches for an appear-ance of high magnitude pulses andpulse series. Magnitude threshold andrepetition in series are configurable.If five events of pulse series weredetected between the scheduledmeasurements, InsulGard will triggera full PD measurement, and display analarm, if any.

Full PD measurement by InsulGardinvolves a measurement of statisticalPhase Resolved Partial Discharge

Distribution (PRPDD) for every activechannel. After each measurement forevery active channel, InsulGard calcu-lates PDI, Maximum PD magnitude, PDpulse repetition rate, and trend param-eters (rate of PD parameter change).The calculated parameters are com-pared to alarm set points and alarmstatus is determined. All calculatedand alarm status parameters arestored in the internal memory foreach measurement. Additionally, threeauxiliary parameters (temperature,% of full load current and operatingvoltage or humidity) are assigned tothe measurement data. PRPDD can,

optionally, be stored in the internalmemory. There are two modes of PDdata storage “Brief” and “Full.”

Full — during this mode PRPDDis stored in the memory with thementioned above parameters foreach active channel and everymeasurement.

Brief — in order to save a memory,

PRPDD can be stored in the memoryseveral times a month. An operatorshould set a number of days and ameasurement number at the currentday for storing PRPDD. During theremaining measurements InsulGardwill store the brief version of PD data.

InsulGard has two Megabytes of inter-nal flash memory for data storageallowing for its standalone operation.When the memory is filled, the devicestarts replacing the oldest data withthe latest data. The rate of the memoryconsumption depends upon a numberof active channels, frequency of mea-

surements, and frequency of PRPDDstorage. As an example, if all 15 chan-nels are active for measurements fourtimes a day and PRPDD are storedtwice a month, the device holds 17months of the latest PD data in itsinternal memory. All stored dataand settings can be accessed fromthe keypad, or remotely from a PC.

AlarmsInsulGard has two configurablealarms, Red and Yellow that connectto two C-form relays. There are twogroups of parameters that can gener-ate an alarm. One is if an alarm set

point is exceeded (Partial DischargeIntensity (PDI) and its trend or PDpulse magnitude and its trend).One of two, PDI or Magnitude,can be configured for alarm at onetime. The same parameter is config-ured for 4 – 20 mA interface outputautomatically. 4 – 20 mA outputprovides a signal with the slope of 10%of Red Alarm Threshold per 1mAmp.That means that Red alarm thresholdcorresponds to 14 mA output.

Alarm set points for PDI are repre-sented in terms of mW. Magnitude isrepresented in terms of mV.

Trend is set in terms of times per yearfor both PDI and Magnitude. Alarm ontrend is enabled after a training periodof 1/3 of the trend-sliding window.

Yellow and Red alarms operate differ-ently. In the case of a Yellow alarm, itwill appear on the corresponding relayas received. In the case of a Red alarm,InsulGard will initiate an additionalmeasurement at the time of alarm,and only if confirmed, will indicate thealarm by relay. If the Red alarm is notconfirmed, the status of the alarm willbe set per the last measurement. If atany measurement the alarm status willbe reduced, InsulGard will indicate thereduced alarm status with both analarm LED reading and relay.

Alarm relays can operate in twomodes (configurable). Relays lock inan alarm status received at the lastmeasurements, until the next mea-surement. Or a relay can operatefor a limited configurable time andthen open the contacts. At the nextmeasurement, if an alarm status is

detected, relays will hold the alarmcontacts closed for the same time.

TrendInsulGard calculates trend of a param-eter enabled for alarm. Trend is nor-malized to the value of the parameterchange in times per year. Trend hastwo alarm thresholds, Yellow and Red,connected to alarm relays and also tothe alarm status LED at the front panelof the device. Trend is calculated as alinear approximation of data overspecified time interval (default is18 weeks). This 18-week time windowis sliding over time while devicemonitors partial discharges.

Continuous Watch FeatureBetween the scheduled measurementsthe Continuous Watch feature (“HighAlarm”) is initiated. At this time allsignal sensors are summarized andconnected to the separate High Alarm

channel. InsulGard is continuouslywatching for the events of high magni-tude pulses (configurable) and theirseries. If five series of such eventsare detected, InsulGard starts fullPD measurement and, in the case of Red alarm confirmation, InsulGardindicates this alarm and stores full PDdata in the internal device memory.

SchedulePD measurements can be performedat specified times during a day ortime interval basis (configurable).The device is shipped with “timebasis” schedule enabled and set torecord measurements four times aday. This is sufficient for all commonapplications.

If necessary, InsulGard can be set tomeasure up to 50 times per day atscheduled times or in specific timeintervals varying from 1 minute to 23hours 59 minutes.

The number of RFCTs required is determined by whatcables the customer wants to protect (to protect secondarycables leaving the switchgear, incoming feeder cables tothe main breaker/switch, etc.). There will be one RFCT percubicle to protect the cabling (even if there are multiplecables per phase).

The length of cable or “sensitivity zone” of protectiondepends upon the type of cable, the number of splices,and the number of taps. PLIC Type Cable is protected up tomaximum of 1500 ft. EPR (rubber composition) distancesare shorter with protection up to a maximum of 300 ft.These are this “Rules of Thumb,” and splices/taps reducethe protected distances. For closer approximations, pleaseprovide exact cable lengths, cable types, and number of splices/taps to Eaton.

Typical Installation of RFCT Sensor

In figures shown above, the lnsulGard is protecting the(6) vertical section switchgear layout with the (2) sets of coupling capacitors and is protecting the feeder cables viathe RFCTs installed on the power cable shield. An explodedview of the RFCT is also shown.

Motor ApplicationsGenerally, the Motor Application components list consists of just the InsulGard Package itself. In some applications, thecustomer may want to monitor the cable feeding the motor.In those cases, one will need to add line item for the appro-priate RFCT.

InsulGard Systems for Motor Applications are sold as “pack-ages.” Packages provide greater value. Standard Equipmentwith the lnsulGard Motor Package is shown in Table 4.5-9.
