At present, the vast majority of relay protection devices depends on a reliable on-site power supply to work. Its power supply of work and operation circuits require substation or distribution room to provide AC or DC power supply. This paper introduces a design of self-supply power source applied in digital relay. The energy is obtained directly from the… CONTINUE READING
