This paper introduces the importance of line protection measurement and control device, the maintenance content and principle of relay protection device calibration. Combined with the practical experience and theoretical knowledge of field cases, a series of measures are taken to eliminate and reduce the incorrect actions of relay protection, so as to ensure the safe and stable operation of the system.
