Product Description

HV high voltage hipot withstanding voltage tester Variable Frequency Series Resonance Test Set 30~300Hz AC Resonant Test System with Low Partial Discharge
I. Product descriptionThe Partial Discharge High Voltage Variable Frequency Resonance Test System is composed of partial discharge variable frequency power, partial discharge exciting transformer, pd free HV reactor and pd free capacitive voltage divider. The partial discharge level could be controlled within 5pC at rated voltage . The regular ac resonant test set is made up of variable frequency power source, excitation transformer, HV reactor and capacitive voltage divider. The capacitor and reactor of test object formed a serial resonance connection. The voltage divider is in serial connection with the test object and used for measuring the resonance voltage and acting as the overvoltage protection signal. The frequency modulation power output is coupled to series resonance circuit via excitation transformer to provide the exciting power.
This high voltage test equipment does not have a problem of large starting current. The power supply with small capacity is capable of fulfilling the test equivalent to 30 to 60 times of the power supply. This greatly solved the problem of poor capacity of test power at site.
