high-voltage switchgear Hi-pot

A hipot test, also known as dielectric breakdown, is a simple test: Apply high voltage to the insulation barrier of the DUT and ensure there is no breakdown. It is a simple pass/fail test—no need for data. Then why are more and more manufacturers requesting the capability to collect data from hipot test?

  • 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.

  • Should I use a high-pot or a megohmmeter?

    In contrast, a high-pot uses higher voltages and currents, and while it can provide a measurement, its primary function is to identify and kill the weak; like taking marginal equipment out of service by breaking down weak insulation before a costly malfunction occurs on the job. Testing can be performed in DC or AC voltage.

    Insulation Resistance Measurement Test. The insulation resistance measurement test may be conducted on all types of electrical switchgear using the insulation resistance megohmmeter commonly known as the MEGGER. High-Potential (Hi-pot) Test. DC Hi-Pot Test. The DC hi-pot test is normally not made for AC electrical switchgear and therefore may be considered only when AC hi-pot cannot be performed. Power Factor Testing. The power factor testing of an insulation system is useful in finding signs of insulation deterioration. The absolute values of power factor measured have little significance. Circuit Breaker Contact Resistance Measurement Test. Stationary and moving contacts are built from alloys that are formulated to endure the stresses of electrical arcing.

  • AC Hipot Testing

    Hipot testing uses a high voltage source to make sure insulation is doing its job. An AC hipot test uses a voltage source that continually changes its voltage. The voltage alternates from positive to negative and back again. Generally there are 50 or 60 complete cycles of the alternating voltage each second.
