Abstract
The negative sequence current protection of three-phase asynchronous motor is a protection that reflects the asymmetric fault of the motor,but it is also affected by various external factors.Therefore,it is necessary to find out all the reasons for generating the negative sequence current of the motor and conduct qualitative and quantitative analysis,so that the protective device can correctly set the setting value to reflect the asymmetric fault of the motor.关键词
