摘要
电流互感器极性测试是新上电流互感器投运或电流互感器重新安装后必须进行的试验项目。电流互感器极性测试仪是为了解决传统电流互感器极性测试耗时、费力、效率低下等弊端而研制的。通过实验室和现场测试验证,利用电流互感器极性测试仪对110kV变电站的CT测试可节省大量人力物力。本文就电流互感器极性测试仪研制方面的内容进行了分析探讨,以供参阅。
The current transformer polarity test is a test item that must be carried out after a new current transformer or current transformer is reinstalled.The current transformer polarity tester is developed to solve the drawbacks of the traditional current transformer polarity test,such as time-consuming,laborious,and inefficient.Through laboratory and field test verification,the CT test of the 110 kV substation using the current transformer polarity tester can save a lot of manpower and material resources.Based on this,this paper analyzes and discusses the development of current transformer polarity tester for reference.
