590G-V2在GIS电流互感器误差测试中的运用

590G-V2 Work on Error Test of GIS CT

GIS广泛应用于110kV及以上电压等级电站。由于GIS的结构原因使得测试内部电流互感器的一次回路长、阻抗增大,影响了内部电流互感器误差测试。本文提出用590G-V2对GIS电流互感器进行误差测试,介绍了590G-V2的原理及其在GIS电流互感器测试中的应用,理论和试验验证了590G-V2测试GIS电流互感器误差的可行性,解决了现场GIS电流互感器测试设备笨重、繁琐等问题。

GIS is widely used on 110kV and the above voltage range substation.The specialty of GIS CT is hard for accurate test on field.This paper introduces the theory of 590G-V2 and the specialties of GIS CT during the accuracy test on field.Via theory analysis,lab tests and field tests,validated 590G-V2 is acceptable for GIS CT accurate test.It can solve the problem of field GIS CT error test.
