    AC Or DC Hipot?ArcingLine RegulationRampingMin/Max Current Detection Or Setting Low/High Current LimitsThe voltage used in a hipot test can be either AC or DC, depending on the requirements established by the regulatory testing agency. Both have their advantages and disadvantages. The typical rule of thumb used to select an AC or DC test is if the DUT is powered by AC, then use an AC test; if it is powered by DC, use a DC test.With an AC hipot test, a long ramp time is usually not required (except with certain sensitive devices). AC testing also has the advantages of checking both polarities o...

  • Hi-Pot Test Current, Leakage Current and Insulation

    Insularion ResistanceLeakage CurrentHi-Pot (Dielectric Strength) TestConclusionsInsulation resistance is the resistance of an insulation. Insulations do not have an infinite resistance. They appear infinite because ordinary ohmmeters do not have sufficient range to measure values in the gigaohm and teraohm regions, which are typical resistance ranges for insulation. An ohmmeter is simply a dc voltage source, a precision resistor, and a current meter. Ohmmeters operate by measuring the current through the series circuit of the precision resistor and the resistor under test. They use a small dc voltage, about 1 volt, to provide the current. Here’s an experiment: Connect the terminals of an ohmmeter and a dc voltmeter together. The ohmmeter will measure the voltmeter input resistance, and the voltmeter will measure the ohmmeter voltage. The voltmeter input resistance will be about 10 megohms, and the ohmmeter voltage will be about 1 volt dc. To measure insulation resistance, the ohmmeter voltage must be much higher than 1 volt in order to get enough current for an...
