AC/DC Hipot tester , Testing Transformers

Introduction:

AC DC HIPOT Tester is applied to test the insulation ability of electric power equipments and insulation materials

at power frequency high voltage. Also the HIPOT tester is a universal power source in HV test.According to the insulation materials of the HV transformer, there are three kinds of HV transformer: Dry HV transformer, Oil HV transformer and SF6 gas HV transformer.

For the dry HV transformer the insulation material is epoxy resin.

For oil HV transformer the insulation material is insulation oil.

For SF6 HV transformer the insulation material is SF6 gas.

The dry HV transformer is smaller in size and less in weight than oil HV transformer. But the maximum output voltage is less than100kv for dry HV transformer.
