A current transformer also isolates the measuring instruments from what may be very high voltage in the monitored circuit. 同时，电流互感器还可以起到在监控回路中，将测量仪器与大电压隔离的作用。
Current transformer saturation has always been one of the major problems of degraded reliability of the transformer differential protection. 电流互感器饱和是影响变压器差动保护可靠性的重要因素之一。
