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 the difference between AC and DC hipot testing?
DC Hipot testing can often be substituted for AC Hipot testing. The optimal voltage for DC hipot testing is usually 1.414 times higher than the AC test voltage. A product tested at 1500V AC will be tested at 2121V DC.
