Surge and Hipot Testing

Surge and hipot testing are additional non-destructive tests which involve applying high voltage to uncover insulation defects and weaknesses.

  • Surge tests are used to detect shorted motor conductor turns, which are typically caused by the failure of conductor insulation, or inadequate insulation on the windings.
  • Hipot tests are used to detect current leaks created by a breakdown in the insulation or material and workmanship defects in and around current-carrying conductors.
