摘　　要：电流互感器的特性不符合要求时常会造成保护的拒动和误动 ,严重影响电网的安全稳定运行 。Because current transformer characteristics cannot meet the actual requirement of relay protection equipment,these equipments often wrongly or cannot operate to protect power network,the network's safety and stability are affected seriously.These effects of current transformer's characteristics on relay protection are analysed and then measures to solve this problem are proposed.

关 键 词：继电保护 差动保护 电网 电流互感器
