The Modelling of the Electric Field Generated by the Electrical Transport Lines

This paper presents the basic concepts regarding the electrostatic effect of the electrical transport lines on the electrical lines located on the same electrical support pillar. The influence of the electrical transport lines on the neighbouring lines can be: electrostatic, given by the electrostatic field and electromagnetic, given by the electromagnetic field. Depending on the position and the configuration of the electrical lines, the induced voltages and the electric field can be calculated analytically or numerically (by using the Quick Field application).Two configurations are analysed analytically: inductor line – one-wired induced line and one-wired inductor line – two-wired induced line. The graphical results (the electrical potential and the electrical field of the one-wired inductor line and one-wired induced line) of the experimental simulations (inductor line – one-wired induced line and one-wired inductor line) are presented in the Quick Field application.
