摘要：
The loss power of ground wires under different phase currents is deduced using the mutual inductance formula, based on which, a method of extracting power from the overhead ground wires is proposed for the sectionalized ground wire network. A power extraction equipment is designed based on the proposed method. The equipment has the characteristics of large input dynamic range, high conversion efficiency and strong anti-interference ability. When the wire load meets the requirements, the power extraction equipment can replace the photovoltaic power supply to realize stable power supply for on-line monitoring equipment. © 2019, Electric Power Automation Equipment Press.
