Research on automatic detection method of secondary circuit connection of the measuring device mutual inductor

Due to the influence of connection distance between mutual inductor primary circuit and metering device secondary circuit, detection induced current traditional method is extremely small, which cannot accurately detect authentic situation wiring, resulting in long time low accuracy. Therefore, this paper proposes automatic inductor. Through voltage sampling measurement data are obtained. Using pulse signal shaping function ADE7753 chip process data, fault judgment determined. According judgment, electric energy meter used, combined with achieved by calculation. The experimental results show that compared method, designed achieves normal stable induction current. There no inductive an small condition, accuracy high, short, indicating suitable for application actual projects.
