电流互感器现场检定常见问题分析

Analysis of Common Problems in Field Test of Current Transformer

由于受现场检测环境、空间距离以及作业条件的影响,常常会出现现场检定的电流互感器误差超出其限值范围、一次回路电流达不到额定值等问题,从而影响对现场电流互感器性能的准确判断。针对以上问题详细分析产生问题的原因,并针对各种因素提出了具体的解决措施,从而实现对现场电流互感器整体的准确判断。

To the problems of the error beyond the error limits and the primary current lower than the rated value in current transformer testing,which were caused by the impact of field test environment,spatial distance and operating conditions,a detailed analysis of the reasons for the above problems was carried out,and the relevant treatment methods were put forward,so as to ensure the successful completion of the field test of current transformers.
