The ultra-low frequency high voltage generator(VLF Hipot Tester) is suitable for: voltage withstand test of XLPE insulated power cables / voltage test of hydroelectric generators and large generators. The 0.1Hz ultra-low frequency insulation withstand voltage test is actually an alternative method of the power frequency withstand voltage test. Especially in the power frequency withstand voltage test of large generators, cables and other test products, it plays a significant role.
When selecting the VLF Hipot Tester, it is generally said that the voltage peak value, our ultra-low frequency display is the peak value, such as HZDP-80KV, which means that the voltage peak value is 80KV, and the voltage effective value is 80KV÷1.414=56KV
