Series resonance device is mainly designed and manufactured for communication voltage endurance test of 11kV/30MW hydro-generator. Two separate designs are adopted for reactor. Series resonance device is mainly composed of frequency conversion control power supply excitation transformer reactor and capacitor voltage divider.
