Power frequency electromagnetic field (PFEMF) is an important part of the ultra high voltage alternating current (UHVAC) transmission line's electromagnetic environment. In this paper, the distribution of PFEMF was obtained by finite element method, and the influence of lines' configuration, vertical height and the distance between phases was discussed. Furthermore, the electrostatic induction was calculated and analyzed, which includes distorted electric field around human body, induced current density within human body and the special characteristics of electric field in rainy weather. The results and conclusions in this paper can be treated as reference for the evaluation of UHVAC transmission lines' electromagnetic environment.
