| Abstract: | The paper presents some examples that generator and main transformers undergo serious over-voltage and over- excitation due to AVR failure, imperfect configuration and irrationality of setting calculation of relevant protection. Discussed in detail are over-excitation and over-voltage, over current, low excitation and the setting calculation of AVR protection. In order to assure generator and main transformers to run safely,feasible measures to improve and consummate the function of protection are put forward. |

| Keywords: | AVR protection over current over excitation over voltage low excitation setting calculation |
