HZTC HV Hipot Control Unit

I.Outline

HZTC series control station is a complete set of equipment of high voltage test

transformer, it and the test transformer carry out resistance pressure and leakage test.

This product is in according with electric industrial standard DL/T848.2-2004.

II.Main Characteristics

This series product has characteristics, such as beautiful appearance, small volume,

light weight, simply operation and conveniently maintenance.

This series control station is consists of touch type voltage adjustor and circuit on

control, measure and signal. After goes through work frequency power 230V/400V, adjust

the output voltage of voltage adjustor(namely the input voltage of test transformer), then

accept the required test high voltage(the pressure value which is tester

），

which work

principle is as the follow drawing.
