Switchgear aging resistance

The switchgear’s resistance to

aging depends upon 3 factors.

■ The necessity of correct

implementation of

connections:

New cold-shrink or slip-on

technology offers ease of

installation.■ The effect of the relative

humidity factor:

Heating resistor installation

is essential in climates with a

high rate of relative humidity

and with significant

temperature differentials.

■ Ventilation control:

Provide area ventilation,

heating, and air conditioning

to maintain the ambient

temperature around the

equipment between - 5 °C

and 40 °C.

Operation It is strongly advised to periodically carry out(minimum every 2 years) a few operation cycles on operating devices.

Outside normal conditions of use (between - 5 °C and 40 °C, absence of dust, corrosive gas, etc.), it is recommended to verify the steps to be taken in order to ensure correct functioning of the installation. Contact the Schneider Electric Service Center for help to do so.

The Service Center is able to

assist you at any time to offer

you:

■ installation diagnostics.

■ suitable maintenance

operations.

■ maintenance contracts.

■ adaptations.

RVAT (reduced voltage autotransformer)

Description The Reduced Voltage Autotransformer (RVAT) is used to provide a

reduced voltage to the motor terminals during starting. This is achieved

by the use of an autotransformer. Typically two types of

autotransformers are available.

■ Tapped—permits changing taps to change the output voltage to the

motor terminals

■ Non-tapped—specifically designed for the application and motor

In this manual, the tapped autotransformer is shown and discussed. For

an application using a non-tapped autotransformer, all information

provided is applicable other than the instruction for changing the tap

settings.

The section size of an RVAT is dependent upon the transformer rating.

The RVAT is always controlled from a main contactor section adjacent

to the left and the motor cable connections are made in this line

contactor section.

Each RVAT section is equipped with the following:

■ run contactor

■ start contactor

■ autotransformer

■ surge arresters

Limited duty cycle rating The reduced voltage starters contain an autotransformer with a limited

duty cycle rating. Unless otherwise noted, these devices are rated per

IEC 60076-11. Longer start times or more frequent starts will shorten

the life of this device.

Keylocks on an RVAT

Keylocking with disconnector (without cable earthing switch)

The RVAT section is supplied with key interlocks between the

disconnector in the main contactor section and the start and run

contactor compartments and the autotransformer compartment.

With the disconnector in the CLOSED position, the key is held

captive. During maintenance, the disconnector can be OPENED/

earthed and the key removed for access to the RVAT section. See“Disconnector operation” and “Accessing the medium voltage compartments RVAT or RVSS soft start section”.

Keylocking (with cable earthing switch)

When a cable earthing switch is supplied, the RVAT section is

supplied with key interlocks between the cable earthing switch in

the main contactor section and the start and run contactor

compartments, and the autotransformer compartment.

With the cable earthing switch in the OPEN or unearthed position,

the key is held captive. During maintenance, the cable earthing

switch can be CLOSED/earthed and the key removed for access to

the RVAT section. See “Cable earthing switch operation (optional)” and “Accessing the medium voltage compartments RVAT or RVSS soft start section”.

A spare key is supplied with every RVAT section. For safe operation, only 1 key should be used. The spare key should be stored away from the equipment and only used if 1 key is lost.

Using both keys could give access to live parts and could cause death or serious injury.

6746032-700-09F.fm


RVAT operation

Autotransformers Autotransformers are normally tapped at 50%–65%–80%. The standard

factory setting used is 65%. Standard reduced-voltage starters make

the transition from reduced to full voltage based on the operation of a

current transition relay. As the motor accelerates, the current drawn will

decrease. When the motor is near full speed, the relay will sense the

drop in current and initiate the transition to full voltage.

Relay setting The current transition relay setting is user selectable with 100% being

the recommended default setting. An incomplete sequence timer will

open the starter if the current relay has not initiated transition before the

timer times out. The timer should be set to a maximum of 30 seconds.

The current relay setting may be increased to its maximum value of

120% if transition does not occur.

Tap setting If the starter does not transition in 30 seconds with the current relay set

at its maximum of 120%, the motor does not have sufficient starting

torque for the connected load. The motor must be unloaded or the

starting torque increased.

To increase starting torque, the autotransformer must be moved from

the 65% tap setting to the 80% tap setting.

steps to change tap settings

❏ OPEN the main contactor controlling the equipment by pressing the

STOP or OPEN pushbutton on the operating panel of the main

contactor. See “Operating the contactor”.❏ OPEN the disconnector in the main contactor to the earthed position.

MDT107 thermal diagnostic system (optional)

The MDT107 Thermal Diagnostic System is mounted in the equipment

at the factory for shipping. Wiring connections must be completed and

tested on site before putting the equipment into service.

Description The MDT107 Thermal Diagnostic system is used to measure the

temperature of medium voltage circuits. Using Schneider Electric

patented technology, the MDT107 system provides:

■ continuous monitoring of temperature rise of power circuits at upper

fuse holders and customer cable connections.

■ triggering of a pre-alarm, then an alarm by activation of outputs on

dry contacts.

■ visual indication of the zone and phase in which a temperature rise

exceeds a set threshold.

The MDT107 system includes:

■ An MDT107 electronic module mounted on a DIN rail in the LV

cabinet of the Motorpact™ unit. The module transmits calibrated

impulses to 1 or more circuits via optical fibers. The calculation of a

circuit’s temperature is based on the impulses the circuit sends back

to the module.

■ 2 CFO733 temperature sensors. Each of these factory-built

assemblies includes 3 sensor heads, 3 optical fibers, and the

connector for connecting to the readout module. The sensor heads

are made from a light-sensitive material whose fluorescence time

depends on temperature. The connector incorporates an optical-

electric conversion circuit, eliminating the need for optical

connections during installation.

■ Accessories for factory installation of the sensors in the MV panel.

7546032-700-09F.fm


Functions The MDT107 module performs the following functions:

Monitoring of temperature buildup in 2 zones

Each CFO733 sensor corresponds to a 3-point zone to be monitored in

the panel, monitoring being based on temperature rise. The module

measures the temperature at 3 points per zone, as well as the ambient

temperature in order to calculate the temperature rise for each point.

Given the temperature differences between the inside of the LV cabinet

and the outside of the enclosure, correction of the ambient temperature

measured by the module is configured by means of an additional

setting.

Comparison monitoring is used with a maximum temperature rise

threshold, which may be adjusted separately for each zone and is

common to the 3 measurement points. This form of monitoring is

completed by a fixed maximum absolute sensor temperature threshold.

Therefore, the module includes 3 settings, to which access is sealed after

the ambient temperature settings are made on site.

Triggering of a pre-alarm When the temperature rise at 1 of the 3 points reaches a first set point

equal to 85% (1) of the preset threshold for the zone, or when 1 of the 3

points reaches the maximum absolute temperature of 115 °C

(239 °F), a pre-alarm is generated that results in:

— activation of the pre-alarm indication relay common to the

2 zones.

— activation in flashing mode of 1 of the 6 front panel indicators that identify

the zone and related point.

Triggering of an alarm When the temperature rise at 1 of the 3 points reaches the preset

maximum threshold (2) for the zone, or when 1 of the 3 points reaches

the maximum absolute temperature of 120 °C (248 °F), an alarm is

generated that results in:

— activation of the alarm power relay common to the 2 zones.

— activation in constant mode of 1 of the 6 front panel indicators that

identify the zone and related point.

(1) This is a fixed value; it can not be modified.

(2) These 7 setting values are defined at the factory. They are identified as A to G. See “Wiring and operation for MDT107”.

76 46032-700-09F.fm


Self-monitoring of the module The MDT107 module has internal self-tests and is equipped with an

indicator that indicates availability:

Availability

indicator

— each time the module is initialized. The indicator

turns on in constant mode when the module is

switched on and then turns off after the module

initialization phase is successfully completed,

unless the required sensors are missing (see “Self-monitoring of sensors”below).

— in steady-state operation. If a fault is detected, the

indicator turns on in constant mode.

In both cases, the pre-alarm output contact is also

activated when the indicator is steadily on.

Self-monitoring of sensors The module provides continuous monitoring of the connected sensor(s).

An “Off” position is included in the settings for each zone for the various

situations that can occur:

■ If no sensors are connected to the module, the:

— indicator is on and flashes

— pre-alarm output contact is activated

— 6 sensor identification indicators are off

■ If 1 of the 3 points of each sensor is detected as being faulty (cut or

damaged fibers, malfunction of sensor-embedded electronics, etc.), the:

— indicator is on and flashes

— pre-alarm output contact is activated

— indicator linked to the faulty measurement point flashes

■ When only 1 zone is connected, the unused zone should be set to

“Off”. If this is not done, the 3 points of the related zone are detected

as being faulty.

Inspecting the equipment

This product is warranted per “Square D Conditions of Sale”, see Schneider Electric document 0100PL0041, and has been tested

under ideal laboratory conditions to the values listed below:

■ 1000 mechanical no load operations

■ 3 fuse fault transfer current operations (see IEC 62271-105C for

application)

Motorpact™ has been designed and tested to IEC 60470 and related

IEC standards. The mechanical life of the disconnector is 5000

operations.

To verify the contact life of the contactor, see Schneider Electric bulletin 46032-700-02, Motorpact™ 200/400/450 A Vacuum Contactors.

To ensure the starter is properly maintained, perform at least the

following inspection procedures:

Busbar connections: De-energize the primary and secondary

circuits. Perform a standard hi-pot test to measure busbar insulation

integrity (see "hi-pot dielectric test" in Schneider Electric bulletin 46032-700-08_, Motorpact IEC Installation Guide).

Inspect the connections for symptoms that indicate overheating or

weakened insulation. Remove dust from the surfaces of the busbars,

connections, supports, and enclosures. Wipe clean with a solvent

such as denatured alcohol. Vacuum the equipment. Do not use

compressed air to blow dust from the surfaces inside the starter.

Maintain the instruments, relays, and other devices according to the

specific instructions supplied. Inspect the devices and their contacts

for dust or dirt; wipe clean as necessary. The maintenance schedule

for individual devices such as meters and relays should be based

upon recommendations contained in the individual instruction guide

for each device. Coordinate the various schedules with the overall

maintenance program.

Inspect control wiring connections for tightness and damage.

Manually operate mechanical moving parts such as switch

assemblies, interlocks, and doors.

Make sure all busbar areas are well ventilated. Inspect grille work

and air passages on starters to make sure they are free from

obstruction and dirt accumulation.

Verify all tools and/or hardware have been removed from the

MV compartment.

Replace all devices, doors, and covers with their original

mounting hardware.
