Surge testing of A/C electric motors and generator windings displays an accurate picture of the winding and insulation conditions. Our tests 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. Our digital surge tester applies a predetermined voltage and captures a sinusoidal wave form for each phase of the unit undergoing 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.
