| Abstract: | During the course of 2~# main transformer's middle-voltage side charging of 110kV Mole transformer,it happens the fault of inside and outside area.Through analyzing the fault phenomena and protection electrical quantity,expatiates the cause of protection action,and validates the action behavior of protection synchronously,it is the simple and intuitionistic analysis method to the analysis course of protection action behavior,and is helpful to maintenance person determining protection action behavior under fault state. |
