摘要
The self-powered technology of the power system measuring device is a power-taking method from the power source to the load according to the principle of electromagnetic induction or energy exchange. Compared with the traditional wired method, it does not need independent power supply to power the device, and has the advantages of high intelligence and high reliability, especially in some special occasions, and will be more widely used. It mainly expounds the existing four mainstream self-powered implementation methods, and analyzes its working principle, transmission efficiency and existing problems. According to the research status of various power supply methods, the future development trend of self-powered technology is prospected.
