    Q1: What is hipot tester?
    A1: AC-DC test transformer, using advanced production equipment, using the coil winding epoxy vacuum casting and CD-type core of the new technology, and similar products compared to oil-immersed transformers, significantly reduce the weight, reduce the volume, in quality to improve the insulation strength and resistance to moisture degree, and effectively weaken the leakage of magnetic and greatly enhance the transformer to withstand the impact of test short-circuit current capacity.

    Q2: Is high voltage testing destructive?
    A2: Hipot (or high potential testing) is a non-destructive test that goes by many names: overvoltage testing, dielectric breakdown testing, dielectric withstand testing, or insulation resistance testing. Some of all of these tests are designed to make sure that the insulation materials used in your motor are doing their job.

    Q3: What is the difference between the hipot and the Megger?
    A3: Both instruments apply a relatively high voltage to the insulator and absorb leakage current through the insulator commensurate with its insulation characteristics and condition. However, the megohmmeter gives the operator a measured value, while the hipot acts.

    Tips: What tests can sisco Hipot Tester be used for?

    1. Insulation resistance test

    Insulation resistance is the most basic insulation index of electrical equipment and circuits , the DC voltage applied to the dielectric, after a period of time after the end of the polarization process, the resistance corresponding to the leakage current flowing through the dielectric is called insulation resistance, the use of DC high-voltage generator to the material under test when the pressure, the current on the material under test will not instantly reach a stable value, but there is a decay process, flowing through a larger charging current, the The high voltage test instrument (DC high voltage generator) is followed by a longer period of slowly decreasing absorption current, eventually reaching a more stable conductive current. The higher the measured resistance value, the longer it takes to reach equilibrium. Therefore, in order to read the measured resistance value correctly during the measurement process, the value should be read after its stabilization.

    2. DC withstand voltage and leakage test

    In order to insulate well, the leakage current under the action of DC voltage is very small, at the same time, at the same DC voltage, the current through the insulation with the extension and decrease, in the case of good insulation, with the increase of the applied DC voltage, due to the speed of ion movement, leakage current increases, leakage current and the increase of the applied voltage is linear, the rise is very small.

    3. Cable DC withstand voltage test

    After the test voltage is three times the rated voltage of the cable, under the specified test voltage, record the leakage current, check the DC high-voltage generator with a high-voltage megohmmeter withstand voltage, the use of conventional connection, a phase connected to a phase with withstand voltage, a phase with a voltage device, the other two phases connected to ground, three-phase resistance for three times.
