Abstract
In this paper, for continuously changed closing time of circuit breakers, switching overvoltage on 345kV underground transmission systems are variously analyzed using EMTP with statistical analysis method. And, switching overvoltage and closing surge occurred in conductors at sending and receiving end and metal sheath with variation of cable length are analyzed, and the reduction effects for switching overvoltage considered preinsertion resistance of circuit breakers are examined.
