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: How does hipot tester work?

Put a voltage higher than normal operation on the insulator of the equipment under test for a specified period of time, the voltage added to it will only produce a small leakage current, then the insulation is better. Program-controlled power supply modules, signal acquisition, and conditioning modules, and computer control system are three modules that make up the test system. Select the 2 indicators of the hipot tester: the value of the maximum output voltage and the value of the maximum alarm current.
