发电机局部电流互感器简便校验方法

Simple Verification Method for Partial Current Transformer of Generator

介绍一种通过修改保护运行方式,在不改变原接线回路的条件下校验局部电流互感器极性和接线是否正确的快速简便判别新方法,该方法有别于传统升流试验,能有效提高局部电流互感器故障检修时恢复速度。

The paper introduces a new method, distinguishing from traditional rising current test, for verifying the polarity and wiring of partial current transformer under the condition of modifying the protection and operation mode without changing the original wiring circuit, which can improve the restoration speed of partial current transformer during troubleshooting.
