摘　　要：为解决空载或轻载变压器投入系统后,难以进行母差保护带负荷检测的问题,因此设计出一种新的试验方法,可以通过变压器的励磁涌流来试验差动电流极性的检查。In order to solve the problem that the loading test of bus differential protection was difficultly implemented after no load or light load transformer put into system. This paper designed a new test method, which tested differential current polarity with magneti- zing inrush current of transformer.
