China High Quality Coupling Condenser Suppliers – Partial Discharge Test System GDYT series – HV Hipot

GIT Series GIS High Voltage Test Sets integrate the high voltage boosting, high voltage measurement, high voltage transformer, high voltage coupling capacitors and all components in a sealed space.
There are two modes to generate high voltage
1) Using reactor inductance and test object capacitance to realize voltage resonance test, to obtain a high voltage, high current from test object.
2) The other one is to obtain required high voltage directly from high voltage transformer.

It is widely used for high voltage, big capacity GIS power equipment insulated withstand voltage test, partial discharge test and GIS transformer accuracy test, suitable for GIS substation, GIS power equipment manufacturer, basin type electrical insulator manufacturer.

Features
