Surge Comparison Tester

Additional Details

Surge testing detects faults in both inter-turn winding and phase-to-phase insulation systems. Using advanced analog-to-digital conversion hardware, the tester captures the surge test waveform, remembers it. This surge waveform storage capability can be applied to other motors besides simple induction motors. The Digital tester can be used to test all the rotating fields of a synchronous motor by storing the waveform from a surge test on one coil, and comparing it to every other coil’s waveform. The digital winding tester can also be used on DC armatures and fields. The resulting waveform can then be compared to all other bar-to-bar or span tests to detect a winding fault.Test results from up to 1000 motors in the field can be stored.
