摘要
差动保护电流回路接线是否正确 ,可通过相量分析法和带负荷检验法进行判断。为此 ,简要介绍了这两种方法 ,举出了计算实例。并指出这两种方法相辅相成 ,在设备安装调试阶段用相量分析法作判断 ,在安装调试结束后用带负荷检验法进行核验。
The wiring correctness of differential protection current loop can be verified using phasor analyzing method and on load testing method. In this paper, these two methods are briefly described together with computing examples. It is pointed out that the former method can be used in the installing and commissioning stage of equipment, while thereafter the latter method can be used to recheck.
