  • What is HIPOT Testing (Dielectric Strength Test)?

    Mar 30, 2021 · The limited approach boundary for this hi-pot procedure at 1000 volts is 5 ft. (1.53m) so place barriers around the terminations of cables and equipment under test to prevent unqualified persons from crossing this boundary. Connect the ground lead of the HIPOT Tester to a suitable building ground or grounding electrode conductor.
