| Abstract: | When an unloaded or light load transformer was put into operation in power grid, in order to solve the problem which it＇s hard to take the bus-bar differential protection load test, this paper designed a new test method. The magnetizing inrush current of transformer was used to take the differential current polarity examine. |
