Method of human body electric shock signal recognition for low voltage power network

Identifying the characteristics of human electric shock is an important premise for power grid safety prevention, power safety protection and the development of leakage protection devices in low-voltage power grid, which should be paid great attention by researchers. This paper analyzes the harm of human electric shock in low-voltage power grid, summarizes and analyzes the human electric shock impedance model, which is based on the human model recommended by IEC60990 and the human Cole-Cole impedance model, Study human impedance $\alpha$ Frequency dispersion characteristics and human electric shock impedance parameter characteristics to realize human electric shock feature recognition. Through the human body simulation experiment under safe voltage, the results show that the effect is good.
