SELF-POWER RELAY AND METHOD FOR PREVENTING MALFUNCTION THEREOF

Disclosed are a self-power relay and a method for preventing a malfunction thereof. A self-power relay of the present invention comprises: a self-power generation unit for autonomously generating a driving power by performing conversion into a preconfigured driving power level by using, as a source power, a system power of a transmission/distribution line or power system; and a relay operation unit operated by a driving power, for measuring the amount of a system power of a transmission/distribution line or power system, blocking a system power transmitted to a load when a failure occurs, andmonitoring a change in a source power of the self-power generation unit in real time, so as to stop a relay operation of the self-power generation unit and a relay operation of the relay operation unit itself when abnormality occurs, wherein a malfunction can be prevented by checking an unstable state of a source current and voltage for generation of a self driving power. 公开了一种自功率继电器及其误动作防止方法。本发明的自功率继电器包括：自发电部，将输配电线路或电力系统
