Safety information

Strictly follow the company and international safety regulations.

Working in a high voltage environment requires serious approch to

aviod human injuries and damage to equipment

Do not touch any circuitry during operation. Potentially lethal

voltages and currents are present

Avoid to touching the circuitry when covers are removed. The IED

contains electirc circuits which can be damaged if exposed to static

electricity. Lethal high voltage circuits are also exposed when covers

are removed

Using the isolated test pins when measuring signals in open circuitry.

Potentially lethal voltages and currents are present

Never connect or disconnect wire and/or connector to or from IED

during normal operation. Dangerous voltages and currents are

present. Operation may be interrupted and IED and measuring

circuitry may be damaged

Always connect the IED to protective earth regardless of the

operating conditions. Operating the IED without proper earthing may

damage both IED and measuring circuitry and may cause injuries in

case of an accident.

Do not disconnect the secondary connection of current transformer

without short-circuiting the transformer’s secondary winding.

Operating a current transformer with the secondary winding open will

cause a high voltage that may damage the transformer and may

cause injuries to humans.

Do not remove the screw from a powered IED or from an IED

connected to power circuitry. Potentially lethal voltages and currents

are present

Using the certified conductive bags to transport PCBs (modules).

Handling modules with a conductive wrist strap connected to

protective earth and on an antistatic surface. Electrostatic discharge

may cause damage to the module due to electronic circuits are

sensitive to this phenomenon

Do not connect live wires to the IED, internal circuitry may be

damaged

When replacing modules using a conductive wrist strap connected to

protective earth. Electrostatic discharge may damage the modules

and IED circuitry

When installing and commissioning, take care to avoid electrical

shock if accessing wiring and connection IEDs

Changing the setting value group will inevitably change the IEDs

operation. Be careful and check regulations before making the

change

About this chapter

This chapter presents the overview of the engineering and operation about

the IED.


2

The Human Machine Interface (HMI) on the IED provides an ideal

mechanism for the day to day operation and even advanced use of the IED.

The keyboard, LCD and LEDs on the front of the IED are what constitute the

HMI. Troubleshooting, monitoring, setting and configuring are all possible via

this interface. Through the screens and menu elements available, as well as

the keypad, the user is able to navigate throughout the menu structure and

move from screen to screen.

The IED is unpacked and visually checked. The connection to the protection

system has to be checked in order to verify that the installation is successful.

The settings for each function must be calculated before the commissioning

task. The functions setting menu have been listed in detail so that the user

can find and change the required settings directly and correctly. For the

different application, the IED can be performed conveniently through

switching the setting group.

For the functions included in the IED can be tested by users, the testing

procedure have been listed as reference to verify that protection function

operate correctly.

After the IED is in service, some checking items also need to be done for

maintenance in order to ensure that the IED is in good condition during

operation, some suggestions have been preset as reference and the user can

perform some other checking items according to the relevant regulations.

1 Unpacking and checking the IED

Procedure:

1. Remove the transporting case

2. Visually inspect the IED

3. Check all items included in accordace with the delivery documents. Once

the IED has been started make sure that the software functions ordered

have been included in the delivery

4. Check for transport damages

If transport damage is discovered appropriate action must be taken

against the latest carrier and the latest SiFang office or representative

should be informed. If there are any discrepancies in relation to the

delivery documents, the SiFang company should be notified immediately

5. If the protection IED is repacked for transport again, the storage packing

of the IED must provide proper degree of protection against possible

damage, in accordance with the standard of IEC 60255-21-1 class 1 and

IEC 60255-21-2 class 1


15

2 Installing the IED

Procedure:

1. Insert the IED into cabinet and the bottom of the IED should be supported

on the frame of cabinet

2. Fix the IED by tightening all screws against the cabinet. The IED should

be fixed in the cabinet and each screw should be firmed

3. Connect the earthing screw on the rear panel to the nearest protective

earthing point in the cubicle. The protective earth cables should be green

or yellow conductors with cross-sectional area 2.5mm2 according to

electrical regulations and electrical standards requirement

The cubicle must be properly connected to station earthing system, using

the conductor with cross-sectional area of at least 4mm2.

4. Power supply module connection

The wiring from the cubicle terminal block to the IED terminals must be

connected in accordance with the established guidelines for this type of

IED. The wires from binary inputs and outputs and the auxiliary power

supply must be routed separated from the current transformer cables

between the terminal blocks of the cubicle and the IEDs connections.

5. Connection to CT and VT circuits

CT and VT are connected to the analogue input module on the rear side

of the IED.

Using solid conductor with cross-sectional 2.5-6mm2 (AWG14-10) or

stranded conductor with cross-sectional 2.5-4mm2 (AWG14-12). The

screws used for fixation conductor should be tightened.

6. Connecting the binary input and output signals

Auxiliary power supply and binary input and output signals are connected

using female connectors. Signal wires are connected to a female

connector, which is then plugged into the corresponding male connector,

located at the rear of the IED.

27

3.1.8 RS232 port

RS232 serial port is located on front panel, the software tool in PC can be

connected with the IED via this port to make setting, testing and cofiguration,

etc.

3.2 Connecting to protective earth

Connect the earthing screw on the rear panel to the nearest protective

earthing point in the cubicle. The protective earth cables should be green or

yellow conductors with cross-sectional area 2.5mm2 according to electrical

regulations and electrical standards requirement.

The cubicle must be properly connected to station earthing system, using the

conductor with cross-sectional area of at least 4mm2.

3.3 Connecting the power supply module

The wiring from the cubicle terminal block to the IED terminals must be

connected in accordance with the established guidelines for this type of IED.

The wires from binary inputs and outputs and the auxiliary power supply must

be routed separated from the current transformer cables between the terminal

blocks of the cubicle and the IEDs connections.

3.4 Connecting to CT and VT circuits

CT and VT are connected to the analogue input module on the rear side of

the IED.

Using solid conductor with cross-sectional 2.5-6mm2 (AWG14-10) or stranded

conductor with cross-sectional 2.5-4mm2 (AWG14-12). The screws used for

fixation conductor should be tightened.

3.5 Connecting the binary inputs and outputs

Auxiliary power supply and binary input and output signals are connected

using female connectors. Signal wires are connected to a female connector,

which is then plugged into the corresponding male connector, located at the


28

rear of the IED.

Procedure:

1. Connect signals to the female connector

All wiring to the female connector should be done before it is plugged into

the male part and screwed to the case. The conductors can be of rigid

type (solid, stranded) or of flexible type.

The female connectors accept conductors with a cross section area of

0.2-1.5 mm2 (AWG 24-15). If two conductors are used in the same

terminal, the maximum permissible cross section area is 0.2-0.8 mm2

(AWG 24-18, each conductor corresponding to one cross section area).

If two conductors, each with area 1.5 mm2 (AWG 15) need to be

connected to the same terminal, a ferrule must be used to combine the

two conductors, no soldering is needed.

Press the locking button by screwdriver to insert the wiring with ferrule

into the connector, move away the screwdriver after the ferrule has been

inserted into the connector completely to lock the wiring tightly. The follow

picture illustrate this process.

Figure 13 Connection illustration without inserting the connector


29

Figure 14 Connection illustration with inserting the connector

2. Plug the connector to the corresponding back-side mounted male

connector

3. Lock the connector by fastening the lock screws

3.6 Making the screen connection

When using screened cables always make sure screens are earthed and

connected according to applicable engineering methods. This may include

checking for appropriate earth points near the IED, for instance, in the cubicle

and/or near the source of measuring. Ensure that earth connections are

made with short conductors of an adequate cross section, at least 6 mm2

(AWG10) for single screen connections.

3.7 Optical connections

This port is used to transmit the binary data between IEDs, there are two

optical ports at the rear side of CPU moduel, Figure 10 and Figure 11, the

two ports works in redundancy communication mode.


30

The fiber optical cables are very sensitive to handling. Do not bend

too sharply. If cable straps are used to fix the cables, apply with

loose fit. Always hold the connector, never the cable, when

connecting or disconnecting optical fibers. Do not twist, pull or bend

the fiber. Invisible damage may increase fiber attenuation thus

making communication impossible.

Strictly follow the instructions from manufacture for each type of

optical cables or connectors.

3.8 RS485 and RS232 ports connection

3.8.1 RS485 port connection

The RS485 interface is capable of half-duplex service with the signals A/A'

and B/B' to transmit signals.

The network topology of RS485 adopts bus type of terminal matched, do not

support ring or star network. Use the single and continuous channel as bus.

The terminating resistance is located on beginning and terminal of the bus

cable. The other ports do not need the terminating resistance.

As shown in Figure 8 and Figure 9, RS485 port located on the rear side of

communication module. The IED provides two electrical isolation RS485

ports, the two ports can work at the same time with IEC60870-5-103 protocol

supported.

3.8.2 RS232 port connection

One RS232 serial port is provided and located on front panel, which is used to

connect personal computer. The RS232 port adopts half-dupex

communication mode, usually which is connected with 9-pin D-subminiature

female connectors

Connection method: direction connection cable for serial port, the IED

terminal is pins and the PC termianl is female connector. The terminal of 2, 3,

4 and 5 is connected directly. As shown in the following picture:


31

Figure 15 Example for serial port connection

The line 4 must be connected directly

3.9 Connecting the GPS

Mount the GPS antenna on the building roof or the place of visibility to all

direction is obtained, top of the antenna should be horizontal. Mount the

antenna to console and fix the console on the building roof with expansion

bolts. The turning radius should not be too small when laying the cables. The

length of antenna cables is designed strictly based on antenna gain, so, it is

not allowed to lengthen, shorten or add connectors that will affect signal

reception or can't receive any signals.

The principle for mounting GPS antenna is that the position is visible

completely to all directions in 360°, however, for some special conditions,

mount the antenna at the place with best visibility as far as possible.

The GPS port is located on the rear side of communication module, as shown

in Figure 8 and Figure 9, which can be connected with screened twist-pair

cable.

About this chapter

This chapter describes the method of hardware testing, such as

power supply, binary input and output, analog quantities and all

functions testing method and testing procedure.


52

1 Introduction

IED test requirements:

Setting value list

The correct IED setting value must have been set before the

testing can start.

Application configuration diagram

Terminal diagram

The terminal diagram and module arrangement diagram,

available in the Technical application manual, is a general

diagram of the IED. but note that the same diagram is not

always applicable to each specific delivery (especially for the

configuration of all the binary inputs and outputs). Therefore,

before testing, check that the available terminal diagram

corresponds to the IED.

Technical application maunal

The Technical application manual contains application and

functionality summaries, function block, logic diagram, input

and output signals, setting parameters and technical data

sorted per function.

The three-phase test equipment

The test equipment should be able to provide a three-phase

supply of voltages and currents. The magnitude of voltage and

current as well as the phase angle between voltage and

current must be variable. The voltages and currents from the

test equipment must be obtained from the same source and

they must have minimal harmonic content. If the test

equipment cannot indicate the phase angle, a separate

phase-angle measuring instrument is necessary.

Prepare the IED for test before testing a function. Consider the

logic diagram of the tested protection function when perform the

test. All included functions in the IED are tested according to the

corresponding test instrunctions in this chapter.


53

The response from a test can be viewed in different ways:

Binary output signals

Display value in HMI

All setting groups that are used should be tested.

The IED is designed for a maximum continuous current of

three times the rated current

Please observe the measuring accuracy of the IED, the

test equipment and angular accuracy for both of them


54

2 Points for attention during testing

Be familiar with the engineering drawings, engineering and

operation manual and technical application manual

Before testing, check that the short-circuited wire used to avoid

CT secondary circuit opening is connected correctly and firmly.

The short-circuited phenomenon of VT secondary circuit does

not exist

It is allowed to plug-in and pull out each module after the power

supply disconnection. Aviod AC current circuit opened when

plug in and pull out the modules

Keep cleaning and pay attention to dust prevention for each

module

Adoption the measure of the human body electrostatic

grounding prevention to make sure that the IED is not

damaged by hunam electrostatic

In principle, the electric iron can't be used in field, if the electric

iron need to be used for welding during testing, the welding

can be performed after the power disconnection or using the

electric iron with earthed wire

During testing, do not insert the module into the wrong position.

When plug in and pull out the module apply appropriate force

instead of overexerting to avoid pins bending or damage the

fastening components of module

Short-circuited or disconnected terminals temporarily for

checking, it should be recorded one by one and return to

original state after the testing is completed

Using the electronic devices (e.g. oscillograph, etc.) with AC

power supply to measure the circuit parameters, the case of

the device should be earthed in the same grounding with

protection IED cabinet

During testing, consider the safety measure between the IED

and other running equipment and the safety measure of

related circuit between external running equipment and the

IED


55

During testing, if the current magnitude that is input into IED is

large than three times of rated current, it should be noticed that

the time should not be too long

When energizing the IED in the first time, using multimeter to

check the power supply, the circuit of voltages and currents are

connected correcly to avoid short circuit or open circuit

Tighten all the screws of all terminals again for the new project

in order to prevent improper connection, and plug in and pull

out all the modules again to aovid the modules loosing result

from operation or installation


56

3 Preparing for test

3.1 Introduction

Please read the corresponding manuals that is provided by

manufacturer in detail before testing, try best to understand the

basic operation, protection principle and the relevant

capabilities. If have any questions in this procedure, please

inquire the field service engineer or the technical support

engineer of SiFang.

All checking should be done before energizing, inspection well

and no damage on the surface, all modules are inserted firmly,

the insulation of the power circuit are satisfied the specified

requirement.

Disconnect the external circuit before testing to avoid safety

accident or injuries to the human

If the modules are needed to be plugged in or pulled out, make

sure that the power is disconnected, and the measure of

prevention electrostatic should be done in order to avoid the

damage to module or performance degradation

The opened or short-circuited terminal temporarily should be

recorded in detail in order to return to original state reliably

3.2 Connecting test equipment to IED

Before testing, connect the test equipment according to the IED

specific connection diagram. Pay special attention to the correct

connection of the input and output current terminals. Check that the

input and output logical signals in the logic diagram for the function

under test are connected to the corresponding binary inputs and

outputs of the IED. The testing connection diagram is shown in

Figure 16.

The user must verify that the connections are correct and the

analog signals are measured correctly after connection completed.

Procedure:


57

1. Inject a symmetrical three-phase current and voltage at rated

value

2. Inject a phase-to-phase voltage and phase-to-phase current

at rated value

3. Check that the magnitude and phasor of analog quantities

displayed in LHMI are in accordance with the input values

4. Inject an asymmetrical three-phase current and voltage at

rated value in two phases

5. Check that the magnitude and phasor of analog quantities

displayed in LHMI are in accordance with the input values

6. If the compared value is consistent, perform the testing, if the

compared value is different, check the analog circuit

4 Testing the power supply

4.1 Checking the self-startup performance

Power on the IED, in order to check the self-startup performance of

the IED, energizing the IED with the voltage rised slowly from zero

to 80% rated voltage, at this time, observe the green “Run” LED on

the front panel that should be lighted continuously. After the DC

power disappears, the normal closed contact should be

disconnected, which can be tested using the multimeter, the

contact is show in Figure 12.

4.2 DC power on and power off testing

Changing the DC power to 80% rated voltage, power off and power

on the power supply some times, the “Run” LED on the front panel

should turn off and turn on correspondingly. The normal closed

contact should be in the “on” or “off” state. The contact is show in

Figure 12.

4.3 Checking the expiry date of power supply

When period checking, check the expiry date for the power supply

module, if the power supply module has been used more than 5

years, please replace it.


59

5 Checking the analog channel

5.1 Checking the zero drift

MainMenu/Testing/ViewDrift

In this menu to check the zero drift of CPU1 and CPU2. The zero

drift values of all analog channels have been listed in detail, check

that the zero drift is met the requirement. Generally, the

requirement of the current channels is <0.02A (if the CT of analog

input module is 1A) or <0.1A (if the CT of analog input module is

5A), the voltage channels is <0.1V. If the zero drift value is not

satisfied the requirement, adjust the corresponding zero drift.

MainMenu/Testing/AdjDrift

It is allowed to check zero drift after energizing the IED for 5

minutes, when adjusting the zero drift, disconnect electrical

connection of the IED, test equipment, standard source and

external circuit, make sure that there are no any inputs to analog

terminals, select the menu and adjust zero drift.

5.2 Calibrating

test equipment to the corresponding input terminals, select the

channel need to be adjusted with arrow keys and Set key, set the

adjustment value In and UN, output the analog quantities from test

equipment to IED and comfirm it. If the operation fails, the

abnormity of analog channel and the channel number will be

displayed in the HMI, check the connection, standard value and

version is correct or not.

Note: during testing, if the measuring tolerance of the analog

quantities are large than the required range, check that the testing

connection, testing method and external measurement meter is

correct, the testing source has not wave distortion, before all of the

exteral equipments are checked, it should not adjust or change the

components of the IED immediately.


60

5.3 Checking the accuracy and the linearity of analog quantitis

MainMenu/Testing/ViewScale

After scale and zero drift adjustment completed, check the

measurement linearity tolerance of the IED with test equipment(the

accuracy of analogue output should be no less than 0.5%), and

record the testing result, the requirement:

If the secondary rated current of CT is 5A, inject current 25A

and 10A (the time for these two injected current can't be more

than 10s), 2A, 1A, 0.4A respectively; if the secondary rated

current of CT is 1A, inject current 5A, 2A, 0.5A, 0.2A, 0.08A

respectively

Inject voltage 60V, 30V, 5V, 1V, 0.4V respectively

Observe the HMI display or check the menu described above, the

voltage channel tolerance is less than 0.1V between HMI display

value and measured value of external meter when the voltage is

0.4V and 1V, for the other voltage value, the tolerance is less than

2.5%; the current channel tolerance is less than 0.2In when the

current is 0.08In and 0.2In, for the other current value, the tolerance

is less than 2.5%.

5.4 Checking the polarity of analog quantities

MainMenu/OpStatus/Measure

Connect all current circuits in series and connect all voltage circuits

in parallel. Inject rated current and three-phase symmetrical AC

voltage with 50V, each phase voltage lead 60° to the corresponding

current. Check the scroll diaplay in HMI or enter into the menu

described above, the angle difference of volage of phase A, B, C

should be 120°, the angle difference of current of phase A, B, C

should be 120°, the current should lag 60° to the corresponding

phase voltage (tolerance ≤3°), if the diaplayed quantities are not

satisfied the requirement, check the IED or the connectin of analog

input module.

Inject three-phase symmetrical AC voltage with 50V, inject phase A

current (rated current) that lag 60° to the phase A voltage, observe


61

the magnitude and angle of 3I0 which are same with IA, if the

difference between 3I0 and IA is larger than the tolerance range,

check the IED and the connection of analog input module.

9 Checking before operation

Note: The following items are only for reference. Users should

make the proper operation guideline based on the actual site

conditions

9.1 Checking the LED

Power on the IED, the LED “Run” is lit steadily in green, other LEDs

should be extinguished.

9.2 Checking the display on LCD

In normal operation condition, the information of “year-month-day,

hour : minute : second, magnitude and angle of analog quantities,

channel state, current setting group: 01” should be scrolling

displayed on the LCD.

9.3 Checking the clock

After setting the date and time of the IED, power on and off the IED

with five times in short time, checking the tolerance of date and

time is within the permissible range.

9.4 Checking the voltage and current

Inject system currents (load current must be larger than 0.08In) and

voltages into the IED, and then check whether the magnitude,

phase angle, polarity and phase sequence of each measuring

analog value are correct or not.

9.5 Checking the setting group

Make sure the active setting group is correct.

9.6 Checking the setting

Checking the settings one by one of each group which are possibly


91

used in the actual operation modes.

9.7 Checking the binary input

Check the state of all binary inputs. Particularly ensure that the IED

is not in test mode, meaning there is not a hand type icon displayed

at the upright corner of the LCD.

9.8 Checking the normal operation mode

9.8.1 Trip and close test with the circuit breaker

9.8.1.1 Switching the circuit breaker state by local command

Trip and close the circuit breaker, the corresponding feedback state

of circuit breaker injected via binary inputs should be read out and

compared with the actual state of circuit breaker, the displayed

state should be in accordance with the actual state.

9.8.1.2 Switching the circuit breaker state from remote control

center

If the IED is connected to a remote substation via SCADA, the

corresponding switching tests may also be checked from the

substation.

9.9 Put into operation

If all the checking items described above and the other checking

items need to be performed according to the site condition have

been checked and correct, the IED can be put into operation.

Chapter 7 Operating maintenance

93


About this chapter

This chapter introduces attentions and the required checking, operation after

updating software or replacing modules and the measure for alarm

information.


94

1 Attentions during operating

Warning

Do not disconnect the secondary circuit connection of current

transformer without short-circuiting the transformer's secondary

winding. Operating a current transformer with the secondary

winding open will cause a masssive potential that may damage the

current transformer and may cause injuries to humans.

Caution

Never connect or disconnect a wire and/or a connector to or from a

IED during normal operation. Dangerous voltages and currents are

present that may be lethal. Operation may be disrupted and IED and

measuring circuitry may be damaged.

Note

Strictly follow the power system operation maintenance instruction

or regulations, the following items for reference:

During operating, prohibition the following operation manually:

Touch the parts of IED with electricity

Plug in and pull out each module

Manually operation to the HMI menu:

Testing binary output

Changing setting value

Setting systme parameter

Changing the IP address

Fault occurrence during operation, if the protection IED tripping, the

corresponding LED in front panel will be lighted, and the event reports

will be displayed in HMI; if the auto-reclosing function operate, the


95

corresponding LED will be lighted and the reports will be displayed in

HMI

If the alarming class I appearance during operation, stop running the IED,

record the alarm information and inform the responsible engineer, at this

time, it is not allowed to press the Reset button. If the alarming class II

appearance, record the alarm information and inform the responsible

engineer to analyse and deal with.


96

2 Routine checking

Checking the LEDs status

Checking scroll display information in HMI

Checking the setting group number


97

3 Periodical checking

Check that the inside and outside of the IED are cleanly and no ash

deposition

All components (including the chips, transformer and relay, etc.) of the

IED are fixed well, no loosing phenomenon, the IED apperance is regular

and no damage and distortion phenomenon

The buttons are operated flexibly with good feeling and fixed reliably

All the IED terminals for connection are firmd without loosing

phenomenon, and the marked number are clear and correct

Energizing the IED with DC power supply for several seconds, the green

“Run” LED will be lighted without any alarm or operation lED lighted (if

lighted, press Reset button to reset), the analog quantities is displayed in

HMI

Check the zero drift and scale

Check the operation setting values

Measure the output voltage of power supply

Check the alarm circuit

Check the binary input

Check the tripping and closing circuit

Test the insulation resistance


98

4 Operation after updating software or replacing modules

4.1 Operation after updating software or replacing CPU module

If the IED software needs to be updated or the CPU module needs to be

replaced for some problem that can’t be handled during operation, the

corresponding operation as follows:

Check the address jumper of CPU module is correct, and input and write

the setting values and parameters

Check the CPU software version number and CRC code

Check the zero drift and scale of all analog quantities channel again

Test all the binary inputs and outputs

Check the setting value and setting group

Perform other relevant testing according to the user’s site operating

regulation before the IED is in service

4.2 Operation after updating software or replacing communication module

Downloading the latest version configuration files to the communication

module by software tool

Checking the detail information for the following items:

Checking the communication module version and the software

version

Checking the communication parameter and protocol, etc.

Configuring the communication module configuration according to the

former configuration or enter into the former configuration again

Set the following parameters:


99

The setting value property and communication mode

Set the network address

Set the IED time again

Check the scroll display is correct after energizing

Perform relevant testing operation

4.3 Operation after replacing the binary input or output module

Check the address jumper of the module is correct

Test all the binary inputs or outputs and the related external secondary

circuit before the IED is in service

4.4 Operation after replacing the analog input module

Check the value and polarity of all analog quantities channel is correct

4.5 Operation after replacing power supply module

Check the accuracy of the output voltage

Test the output relay

Test the binary inputs

Chapter 8 Transportation and storage

103


About this chapter

This chapter describes how to transport and store the IED.


104

1 Transportion

The IED can be transported by means of conveyance, such as car, train, ship, etc. In order to ensure the perfect performance of the IED, prevent the IED from rain, snow, vibration, shock and bump.


105

2 Storage

If the IED is to be stored before installation, this is must be done in the original

transport casing in a dry and dust free place. The packed IED should be

stored in a waterproof and snow proof place without acid or alkaline or other

corrosive gas and explosive gas. The storage temperature is from -25°C to

+40°C, and the relative humidity does not exceed 80%. Observe the

environmental requirements stated in the technical data.
