| Abstract: | This paper introduces a method to measure the negative sequence current. The reason to the negative sequence current and the damage to the generator and power system are analyzed. A practicable arithmetic for the negative sequence current in the ground small-current system of two-phase CT connection is given, and the hardware circuit is presented. |
