Testing Type AC DC High Voltage Testing Transformer
I---Introduction
- 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 Hipot 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.

III.Model selection table
- The detail power parameters for the common models HV transformer
are as table 1. Please confirm the right model before order. The
main parameters include input voltage, maximum output voltage and
capacity.
- The parameters in this table are response for HV transformer only
and we will install the main control box according to the capacity
and input voltage of the model you order
