AC test transformer system

AC test transformer system generates a continuously adjustable AC test voltage. It is used for GIS high-voltage switchgears, cables and accessories, instrument transformers, power transformers, high-voltage circuit breakers, coupling capacitors, capacitive bushings, surge arresters, insulators, electrical porcelains and other electrical components in AC voltage withstand, partial discharge test and other scientific research. When the high voltage test needs to be provided a resistive curren...

AC resonant test system(variable inductance)

The AC resonant test system generates a continuous variable AC voltage for testing the HV capacitive object. Capacitive test object includes cables, capacitors, GIS,  generator set, capacitive instrument transformer, etc. The variable inductance resonant test system can be used at 50Hz and 60Hz or even higher frequency. Because of its excellent sine waveform,the system is very suitable for the partial discharge measurement in high voltage AC voltage withstand test. Th...
