The practice shows that due to the fact that the protective relay and the setting value are not chosen and calculated according to the actual conditions of the field, the misoperation and refusal of the motor protection device occur frequently. This paper introduces the constitution of current quick breaking protection and its fixed value calculation, and provides reference for power supply workers. 1. selection of motor protective rela
