Fault Location Method and Hardware Monitoring System of Parallel Compensating Capacitors

At present, the operational parallel compensating capacitors can only through the protection action for the information, so we cant location the fault capacitor. In order to obtain every parallel capacitor running status information and according to internal structure and the operation mode of film capacitor, this paper propose a method of locating a capacitor, and based on this method constructs a set of hardware monitoring system. This method can eliminate the affection caused by the environment and measurement error of sensor accuracy effectively and the hardware monitoring system can solve the insulation problem, which high-potential power supply and wireless collection and transmission technology bring.
