These current transformers may not be the same as used for the differential protection as the varistor may cause rapid saturation of this current transformers.
由于压敏电阻可能使得电流变压器快速饱和，故而这些电流变压器可能与差变保护电压器不一样。
The differential protection for power transformers features less ratio of proper actuation and slow response, because it severely suffers from false differential current caused by core saturation.
变压器的差动保护因受到铁芯饱和引起的虚假差流的影响，其正确动作率较低，动作速度也较慢。
The saturation of magnetic current transformers, occurred during a fault on the power system, will lead to mal-operation or refused operation of protection relay.
电磁式电流互感器在电力系统故障情况下可能发生饱和，常导致继电保护装置误动或拒动。
