Applications Note Best Practices for HiPot Testing of Busbars HiPot testing, short for high potential testing or high voltage testing, is a type of electrical safety test conducted to verify the insulation
Home / What tests are performed on low-voltage busbars
In practice, thermal imaging and ductor testing are used together to assess the health of busbar connections. We carry out full electrical type tests on low voltage busbars in accordance with the IEC 61439-6 Standard to ensure that the products comply with regulatory requirements. This test ensures that the insulation can resist the prescribed voltage stress without failure. IEC 61439 is a standard developed by the International Electrotechnical Commission (IEC) that covers design verification for low-voltage electrical products and assemblies.
