| Abstract: | Differential protection is the main protection action of the transformer. After the transformer put into operation, it is needed to checkout the polarity with load and promised the correct connection. This thesis specifically analyzes the reason of incorrect connection, by drawing the phasor diagram of current in each side with load, and puts forward the correspond countermeasures. |
