变压器套管CT安装后极性测试方法的研究

摘要

Transformer bushing CT polarity is correct or not directly related to the reliability of protection, but also will directly affect the safe and stable operation of transformer after operation. This article in view of transformer bushing CT after installation of traditional test method is dififcult to accurate and sensitive test defects of polar research, independent research and development of four channel polarity tester, and applied to the polarity test tube CT after installation, ifeld application of convenient operation, accurate result and high efifciency.%变压器套管CT的极性正确与否直接关系到保护的可靠性，也将直接影响着变压器投运后的安全稳定运行。文章针对变压器套管CT安装后传统试验方法难以准确、灵敏测试极性的弊端展开研究，自主研发了四通道极性测试仪，并应用于套管CT安装后的极性测试，现场应用操作方便、结果准确、效率高。
