Electric Field under EHV Transmission Lines: Theroretical Analysis and Statistical Comparison and TVA Measurements

摘要

Electric fields under EHV transmission lines are analyzed and compared with TVA measurements. Three electric field models are developed: the level ground plane (LGP) model, the tilted ground plane (TGP) model, and the charge moment method (CMM). These theoretical models are implemented for computer analysis and statistical comparison with the available data. The effects of terrain irregularity and tree shading are progressively incorporated in the hierarchy of models yielding a corresponding reduction in the residual error. 18 refs., 28 figs., 12 tabs.
