This paper firstly summarizesthe research and application status of the wireless power transmission (WPT) technology in high voltage equipment. Some researches of the power suppliesapplied in the high voltage terminal equipment based on wireless power transmission technology are then introduced. The mathematical model of the electromagnetic resonant WPT with relay coil is established. And the optimal location of the relay coil and the transmission power, distance and efficiency aresimulated and analyzed accordingly. It is concluded that the electromagnetic resonant WPT technology with relay coil can meet the power demand of the high voltage equipment and the requirementof insulation.
