摘　　要：随着电网的壮大,变电站原有的电流互感器可能已不再适应要求,需按当前条件重新进行校验。以一个110kV变电站10kV电流互感器的校验为例,介绍了电流互感器的校验过程,供同仁参考。With quickly development of industry and agriculture, the current transformers designed under old condition would not meet nowadays demands more or less. It is necessary to recalibrate under current condition. Taking a current transformer of substation 10kV feeder line as example, This paper introduces the checkout procedure for reference.
