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 is AC DC hipot tester?

AC DC hipot tester is a special instrumentation for field measurement, both DC high voltage and AC high voltage measurement, the whole device consists of two parts: voltage divider and measuring instrument. Voltage divider using balanced equipotential screen structure, the use of top electronic components inside the completely sealed insulation, and make the whole device with accurate testing, good linearity, stable performance, reasonable structure, easy to carry, simple operation, display intuitive characteristics, so it is the ideal instrument for field measurement.
