MOTOR TEST BENCH FOR NO LOAD TEST FOR INDUCTION MOTORS

Motor Test Bench is capable of testing 3 phase, 50 c/s, 440 V Induction motors providing the following scope of tests.

High Voltage test upto 3 kV rms.
Capacity: 500 mA in the H.V. side with tripping at 100 mA, 250 mA & 500 mA.
Duty cycle: 5 mins. ON 5 mins. OFF

Insulation test at 500 V DC & 1000V DC.

Performance tests for induction motors at NO LOAD with application of Rated Input Voltage.
i. No load current characteristic.
ii. No load losses.
iii. Speed of Motor can be checked by external tachometer (not in scope of this contact).

The Test Bench can test-
Single phase motors upto 30 kW Max. On D.O.L. Start.
3 Phase Motors upto 95 kW at 440 V (Line to Line) on D.O.L. Start.
3 phase Motors upto 110 kW at 440 V (Line to Line) on Start / Delta Start.

Input: 3 phase, 50 c/s, 440 AC.

Interlocks are provided to make sure that only one test can be carried out at one time.
Similarly, only one Motor to be tested at one time. Off-load tap changing arrangements
are incorporated in the Test Bench.

Metering:
Voltmeter with phase selector switch for applied terminal voltage (line to line).
Voltmeter to read the applied H.V. & milliammeter to read the tripping current.
CT operated Ammeter for Line currents (for all three phases).
Wattmeter.
Megaohm meter.

Protection:
Bimetal over-load relays.
CT operated overload-tripping circuit incorporating contactors, auxiliary relays etc.
Single phase preventer.

Sets are also manufactured as per customers? requirement.
