保护用电流互感器检定线路浅析

Method to Test Errors of Protective Current Transformers

设计了专门针对保护用电流互感器的检定线路,能完成检定常用电流比互感器、检定特殊电流比互感器、实测二次负荷、增大输出电压和外接电源测伏安特性等五类测试。

In this article,the test circuit specifically for the protection current transformer is designed,by which five kinds of tests can be completed,including testing current transformer with common current ratio,testing current transformer with special current ratio,testing secondary load,testing voltage characteristics by an external power supply and increasing the output voltage.
