【Abstract】 More and more capacitive voltage transformers are out of operation due to the fault of damping circuit,which seriously affects the safety and stable operation of the system. Based on the damping resonance principle and the existing external tap of CVT,a damping circuit testing device is designed. The current of the damping circuit can be read,and the damping circuit state of capacitive voltage transformer with infrared temperature measurement can be diagnosed.更多还原
