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 an AC/DC hipot & insulation tester?
An AC/DC hipot & insulation tester is a multifunctional safety testing instrument that combines withstand voltage (hipot) testing and insulation resistance (IR) measurement in a single device. During a hipot test, the instrument applies a high AC or DC voltage between conductive parts and ground to verify that the insulation can withstand electrical stress without breakdown or excessive leakage current. In insulation resistance mode, it applies a DC voltage and measures the resistance of the insulation to evaluate its quality and integrity.
By integrating both tests, this type of tester provides a more complete assessment of electrical safety and insulation performance. It is widely used in production lines, laboratories, and quality control processes for products such as home appliances, power supplies, cables, automotive electronics, and medical devices. Using an AC/DC hipot & insulation tester helps manufacturers comply with international safety standards and ensures products are reliable and safe for end users.
