A NEW AUTOMATIC TUNING METHOD FOR RESONANCE GROUNDING POWER NETWORK

A new method is proposed to measure the tuning-off degree and the capacitive current of resonance grounding power networks based on a new measuring principle. The measuring is carried out on-line, without starting the tuning mechanism of arc-suppression coils and interfering in power network抯 running. This method is suitable for the real-time detecting and measuring system of power networks. The precise tuning of the arc-suppression coil can be realized on the basis of the precise value of the tuning-off degree and the capacitive current. This method can be used in all kinds of arc-suppression coils.
