The power frequency electric field and Electric radiation generated by high voltage transmission line have a great impact on the surrounding environment, which is one of the important research topic on environmental protection and electromagnetic compatibility technology field. In this paper, the information database of typical transmission line and tower established,and the prediction of power frequency electric field intensity of high voltage transmission line has been given by using the 3-D computational method.Then, the major factors affecting the calculation results of electric field is discussed based on the measured data and the error analysis is given.
