high-voltage switchgear separating unit Hi-pot

To hipot test a net, you connect all of the contacts in the net to high voltage and connect all other contacts in the device to ground. For example, if you have a wire that connects two pins, the high voltage will be simultaneously apply to both of those pins and the entire wire will be raised in voltage.

  • What is HIPOT Testing (Dielectric Strength Test)?

    Mar 30, 2021 · Hi-Pot test is a contraction for high potential HV testing. Hipot Test is short name of high potential (high voltage) Test and it is also known as Dielectric Withstand Test. A hipot test checks for “good isolation.” Hipot test makes surety of no current will flow from one point to another point.
