Digital Surge Testing

Surge testing of A/C electric motors and generator windings displays an accurate picture of the winding and insulation conditions. Tests made can determine good, marginal or defective windings and the winding insulation before a major failure occurs. In many cases actions can be taken to head off these failures, preventing costly delays and repairs. This digital surge tester applies a predetermined voltage and captures a sinusoidal wave form for each phase of the unit under going the test. It also displays megohms and Hi-Pot measurements. All the information is used to make the correct decision on what repairs are needed.

This is a Surge Test

The wave form showing a good winding. You will notice how each of the three phases overlap each other. Representing what appears to be only one wave line. Pictured is the windings that are best tested, no faults are present.

Turn to Turn/Phase to Phase Weakness

If there is a Turn to Turn / Phase to Phase weakness the wave patterns will separate and appear unstable. This is an indication of imminent failure. The motor should be serviced immediately. Pictured in a Turn to Turn / Phase to Phase fault.

Ground Faults

If there is weak insulation the wave pattern will indicate the weakness. If a motor with a turn to turn fault short stays in service circulating currents may produce hot spots and the ground wall insulation will eventually burn up, causing a shut down. Pictured is a ground fault.

Core Loss Tester

Core loss testing has become essential in ensuring quality electric motor and generator repairs. The stator lamination is tested to determine the watts loss per pound of steel magnetic core iron. When electric motor & generator windings fail, they often damage the stator lamination. This causes hot spots to develop leading to premature winding failures. If your company has had an electric motor or generator repaired only to have the machine run hot and burn up after a short time, the most likely cause was a damaged lamination core. This problem will no longer be a cause of concern when this test is performed.

Insulation Stripping Ovens

Stripping ovens are an integral part in the repair process. Water injection temperature controlled burning of electric motor & generator stators alleviate the damage caused if the oven has a thermal runaway, simply put the water injection system keeps the temperature at the present levels overcoming the potential of
