g form of shunt capacitor bank, four kinds of configurationРprinciples and methods of unbalanced protection were discussed. Combined with practice example and the specifica⁃Рtions for equipment selection, it is pointed out that bridge current differential protection should be the priority selec⁃Рtion for large capacity capacitor bank; differential voltage protection is the priority selection for small capacity ca⁃Рpacitor bank; open delta voltage protection is suitable for simple connection capacitor bank; and neutral point unbal⁃Рanced current protection shall be avoided.РKey words Shunt capacitor bank; unbalanced protection; equipment selection; configuration principle; configura⁃Р ：Рtion methodРР 81
