In the paper, electric field under overhead lines with human body existing is studied. The mixed method coupling finite element method with charge simulation method is constructed. Linkage of the finite element method domain and the charge simulation method domain is done by use of surface charge at interface. A simplified model with basic figure of human body is used. Calculation results show that human body has distortion effect on electric field nearby. Electric field at region very close to human body is greatly enhanced, while there’s little influence at region far away from the body. Head and upper side of human body play main roles of induction.
