Using medium voltage carrier communication to achieve full coverage of power information acquisition and distribution automation has become a hot spot in the domestic power industry. The characteristics of 10 kV line will largely affect the reliability of medium voltage carrier communication, but due to the influence of voltage level and other factors, the research on 10 kV line characteristics is not mature. In this paper, a research method of 10 kV line characteristics based on medium voltage carrier is proposed. The improved medium voltage carrier communication machine and coupler can realize the collection of 10 kV line impedance, attenuation and noise, accumulate useful data for the long-term study of 10 kV line characteristics, help to improve the reliability of medium voltage carrier wave communication and assist 10 kV line fault monitoring.
