GIS ( Gas-insulated switchgears )
Test equipment for routine test, type test and on-site test of GIS/GIL should generate a range of testing voltages and power ratings as well as frequencies. Voltage withstand test and associated PD measurement can be performed in the factory. During development and type test, the components are to be tested with impulse voltage.
Test systems for on-site testing are compact and can be installed on a trailer.
