Yan Zhong-hua · Insulators and Surge Arresters · 2005
In the last analysis,the outage at interrupter of station circuit breaker due to invading lightning surges is attributed to induced overvoltage caused by thunder strike,which may be limited by surge arresters installed at line end. Discussion is made on surge arrester installation,selection,monitoring and disconnecting device. A mounting scheme of line surge arresters suitable for dual-circuit line is proposed by the authors. Expected service effect is proved when the proposed mounting scheme is used.
