Three transmission lines of different cconfigurations are modeled and analyzed. The first line is an 800 kV, flat configuration, six bundles and single circuit in South Africa. The second line is a delta configuration, 1050 kV, eight bundles, and single circuit in Italy. The third line is 1100 kV, double circuit, eight bundles, in Japan. The charge simulation method is used for calculating the electric field underneath these lines. The maximum electric field underneath the three lines is 1.9, 2.9 and 2.1kVm-1 for the 800, 1050, and 1100 kV lines respectively. The effect of the phase sequence on the electric field for the double circuit transmission line is also studied and presented in this paper.
