Interesting facts about HV testing, high-voltage testing and insulation resistance measurement
- High-voltage test (HV test) with high-voltage testers
This test is also called HV test or dielectric withstand test. The test is carried out with an AC or DC hipot tester, as required. In the process, the high-voltage testers check the insulation of the electrical devices. In the test, the tester is exposed to a significantly higher voltage than the product requires in normal operation. This test proves that the device under test has a sufficiently high dielectric strength. Thus, the device is safe for the user even at a higher operating voltage than that defined in normal operation.
The so-called leakage current measured in the test must not exceed a previously defined level.
- Insulation resistance measurement
Testing of the insulation or insulation resistance of the device under test to ensure hazard-free operation of the device. The test is carried out between all current-carrying conductors and towards the housing.
