Hipot / High Voltage Tester

High-voltage testers, or hipot testers, ensure the safe use of electrical products. Different working enviroments and operating conditions are tested. Depending on the tests required to meet relevant industry standards, there are a variety of solutions available. Many test units offer a combination of functionalities and features.
Most test units are remotely controllable via PC. This allows testing to be done safely while the unit under test is in a closed enclosure. Furthermore, the test results are digitally documented and can be processed for a certificate.

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 and objects. 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.
