Abstract
The power frequency electric field of the extra high voltage network, as an index which has an important effect on the ecological environment around has been valued by the power design and operate department. Studying the factors that affect electromagnetic environment of transmission line and protective measures can provide technical basis for the design of the transmission line, and make people to recognize the electromagnetic environment of transmission lines correctly and select the rational protection measures. In this paper, firstly the physical model of overhead transmission lines was built and the electric field was calculated, then the actual electric field under 500 kV transmission line in Jiaozuo was measured using the electromagnetic analyzer PMM8053B, finally the correctness of the theory and model was verified using the MATLAB simulation software.
