Abstract：In this paper,the current transformer(CT)is used to get power from the high voltage transmission line directly,so as to solve the power supply problem of the transmission line high voltage side monitoring system under the information operation and maintenance mode of the power grid. The output power of coil induced voltage from the transmission line,the analog output pulse width modulation(PWM)wave control using SCM charging module,3.4V provides a stable voltage for the load,easy to solve the core problem of saturation,power grid operation mode optimization scheme of information. The power supply based on the output power coil is tested comprehensively,and it is verified that it can work normally in the current range of 50-1000A,and it can pro?vide stable output. The protection circuit is also designed to improve the reliability of power grid operation and maintenance,and ef?fectively solve the power supply problem of grid information operation and maintenance online monitoring system.
