摘要：High voltage overhead lines produce intense electric field and induce current in human body which may be hazard to human health. To study electric field of overhead lines and human body, a mixed method utilizing both finite element method and surface charge method is first presented. It can be used to complex structure and open domain. Merged matrix equation is deduced and an example of electric field with analytical solution is calculated for verification of the mixed method. Then electric field of overhead lines with a human body of axisymmetric structure and homogeneous parameters is calculated. Results show that existence of human body has little influence on electric field of overhead lines far away from the human body and there is a great increase of electric field at surface of human body. Induced current in human body varies at different parts of body. There are bigger values at parts of neck and lower body.
