HIPOT tester is applied to test the insulation ability of electric power equipments and insulation materials at power frequency high voltage. The insulation test result of the tester is go or not go. Also the HIPOT tester is a universal power source in HV test. The maximum output voltage and capacity could be customized according the requirements of custom.
The tester is consists of single HV transformer and main control box. There are three kinds of HV transformer according to the insulation materials of the HV transformer. They are 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 has a smaller size and less weight than oil HV transformer. But the maximum output voltage is less than 100kv for dry HV transformer. The functions of the main control box are voltage output regulation, protection in emergency and voltage/current value indication.
