摘要
计量用电流互感器的主要作用是将一次大电流传变为小电流,再传送至电能计量设备。电流互感器的准确度即良好的误差特性直接影响计量设备的测量精度,为此,必须检测其误差性能,进行误差测量试验。
The main function of current transformer for metering is to transfer a large current to a small current and then transmit it to the electric energy metering equipment. The accuracy of current transformer, that is, good error characteristics, directly affects the measurement accuracy of measuring equipment. Therefore, it is necessary to test its error performance and carry out error measurement test.
