数字化变电站电子式电流互感器极性的检测方法

The Way to Measuring the Polar of Electronic Current Transformer of Digital Substation

对数字化变电站中电子式电流互感器极性的正确检测是数字化变电站安全和稳定运行的重要保证。本文通过比较电子式电流互感器与传统电流互感器在定义、原理、二次回路和检测项目上的区别,对传统电流互感器和数字化变电站电子式电流互感器极性的检测方法进行了详细阐述,最后指出确认电子式电流互感器极性的两种检测方法是行之有效,互为补充的。

It is important to Measuring the polar of Electronic Current Transformer correctly to keep the Digital Substation operates safely and stable. In this paper,we compare the different between Conventional Current Transformer and Electronic Current Transformer from definition,principle, Secondary circuit and measuring process.We final confirm that two ways which we point out is effective and complementary by analyzed the ways to measuring Conventional Current Transformer and Electronic Current Transformer in detail.
