Study on transient electric shock characteristics between human body and metal clothes hanger on residential platform near UHV AC transmission lines

With the development of ultra‐high‐voltage (UHV) and extra‐high‐voltage transmission lines in China, the transmission lines are gradually approaching the residential areas. The phenomenon of induced electric shock caused by electrostatic induction effect can cause dissatisfaction and complaints from nearby residents. In this paper, a full‐size steel‐framed residential test platform was constructed near a 1000‐kV UHV alternating current (AC) transmission line, the transient shock characteristics of human bodies and metal hangers in different scenarios was investigated, then the relationship between transient shock energy and subjective perception of the human body was discussed. In addition, the shielding effect of shielding wires for transient electric shock situations is analyzed. It was found that the worst‐case scenario occurred when the grounded human body came into contact with the insulated metal clothes hanger, even eliciting a noticeable sensation of pain. In addition, increasing metal shielding wire number has a significant effect on weakening induced electric shocks. A full‐size steel‐framed residential test platform was constructed near a 1000‐kV ultra‐high‐voltage AC transmission line, then the performances of transient electric shocks when human bodies contacting a metal clothes hanger were investigated. The transient shock current characteristics and correlation between transient shock energy and human perception were analysed. In addition, the shielding effect of shielding wires for transient electric shock situations was analysed.
