用比较测差法检定现场电流互感器常见问题及处理

The Common Problems of Using Comparing Method to Calibrate Current Transformer and the Corresponding Processing Means

本文介绍了用比较测差法检定现场电流互感器时常见的两大问题:1.互感器一次电流升不到规定的电流值。2.互感器检定结果不合格,分析了造成两种问题的各种情况及原因,并提出了相应的处理方法。

Two common problems of using comparing method to calibrate current transformer is described in this paper.One is current transformer＇s primary current can＇t rise to specified value,another is the calibrating result of current transformer is unqualified.This paper analyzes the causes which lead to the two problems and presents the corresponding processing methods.
