Westin Drives invests in portable surge tester

To give our customers the best electric motor rewind service, Westin Drives has invested in a portable, 12kV surge tester. 

This sophisticated device is employed to diagnose problems with motor windings that arrive for repair at our Huddersfield Service Centre. It is also used for the final check on all finished jobs before they are returned to the customer.

Surge tests are vital because they are capable of revealing turn-to-turn insulation weaknesses. Such weaknesses, found at voltages above the operating potential of the device under test, can be signs of the impending failure of a motor. Surge tests are also used to find shorts and other faults in windings and coils.

An added benefit is that it can be taken on site for the swift diagnosis of a problem or trending the condition of a winding over time as part of a predictive maintenance plan.

In addition, the surge tester generates a comprehensive report on the state of each tested winding, which is then provided to the customer.
