Recently, research on the application of wireless power transfer(WPT) technology to electric transportation equipment trough smart road networks has been actively conducted. In addition to research on capacity and efficiency in WPT, it is necessary to review the risks of losses transmission to nearby environment including conductive parts. The path of the electrical hazard to existing electrical equipment located at the transportation station becomes the grounding wire through the induction effect and the stray capacitance effect. Leakage current, one of the major electrical hazard, affects the existing electrical equipment enclosure along the ground wire, which can have a hazardous effect to human body and electrical equipment. Therefore, it is necessary to reduce the induction effect by securing a separation distance from the feeding cable and controlling the parallel section of the ground wire to the feeding cable. In addition, separating the ground wire so that the effect of stray capacitance generated in the power inverter does not affect the existing electrical equipment. For 10 kW WPT system, a feeding current of 60 kHz, 200 A was generated. As a result of the separating distance from the feeding cable, limiting the parallel section, and independent grounding, it was confirmed that the leakage current through the ground wire decreased from about 2.3 A to about 0.3 A.
