| Abstract: | The parallel power condenser can not only compensate reactive power, reduce transmitting loss and improve transmitting capacity, but also play the role of adjusting and stabilizing the electric system. In practical operation, due to the condenser be made in service and out of service frequently and the effect of higher power harmonic in electric system, the abnormal phenomena of power condenser appeared many times in Shizuishan Electric Power Supply Bureau, caused the condenser and breaker broken, threatens safe and steady operation of electric network badly. |
