Hipot tests

The hipot test (high potential test) or dielectric withstand test, is used to determine the insulation and dielectric strength. It is carried out on modules, devices and systems of protection class I + II. In this test, the insulation of the test object is subjected to greater stress by the high voltage than in normal operation. It is determined whether the insulation of all current-carrying conductors, as well as the safety distance to the enclosure, is sufficient and complies with the legal requirements under normal operating conditions.

We will be happy to assist you with any questions or solutions to problems.

You will find a large selection of high-voltage testers in our comprehensive shop.

Questions? We are always at your disposal.

Insulation strength or insulation resistance test

The measurement to determine the insulation strength or the insulation resistance is carried out with DC high voltage between all current-carrying lines necessary for the operation of the product or the system. The relevant limit values for the test depend on the respective product or the corresponding standard.

Dielectric strength test

The dielectric strength test provides information on the extent to which two insulated conductors are able to prevent a flashover after a high voltage is applied. In the event of a flashover, there is a sudden potential equalisation, which can result in sparking or an electric arc. This results in a high current flow, which is equivalent to a short circuit.

Multifunctional safety tests

Manufacturers of electrical or electronic products are required by law to carry out an electrical safety test before placing them on the market. This final test takes place at the end of the manufacturing process and is therefore also referred to as an EOL test (end-of-line).

Depending on the prescribed standard and directive, the following parameters are tested:

  • Leakage current and discharg current
  • Insulation resistance or the insulation strength
  • Dielectric strength or electric strength
  • Correct installation of the protective conductor (ground continuity and ground bond test)
  • Proper functioning of the product under the conditions defined for the intended use (function or run test).

This guarantees the user that there is no potential danger when using the device. With the so-called multifunctional test devices, all necessary test tasks can be carried out with only one test setup. The test procedures can be automated via the associated software. The results can be documented and are reproducible at any time. Multifunctional test devices are ideally suited for installation in test hoods.
