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: Why does Hipot tester have a lower limit current setting?

The hipot tester on the production line is used very frequently, especially the test line, test fixture, etc. are often in an active state, which is easy to cause the internal core wire to break and open, and it is generally difficult to find. As long as there is an open circuit at any point in the loop; the high voltage output by the withstand voltage tester cannot really be added to the object under test. All these reasons will result in that the high voltage set is not really applied to the tested object during the withstand voltage test. Naturally, the current flowing through the tested object is almost zero at this time. If the value is set, the instrument will give a prompt that the test is qualified, and consider that the insulation is qualified. But the test data in this case is unreal. If the measured object at this time happens to be defective in insulation performance, it will cause serious misjudgment.
