Sažetak
Three different two-dimensional (2D) algorithms for the computation of the electric fields of both overhead power lines and buried cable lines are described and compared. The first algorithm developed in this paper takes into account a short straight overhead power line and approximates the conductor charge density by a parabola. The second algorithm takes into account a short, straight power line and approximates the conductor charge density by a constant. The third algorithm is based on a simplified approach that analyses an infinite, straight power line. Furthermore, two different 2D algorithms for the computation of power line magnetic flux density are described and compared. One of these algorithms takes into account the short, straight overhead or buried power line, whereas the other takes into account an infinite straight power line. The effect of neglecting the shield wires in the electric field intensity computation is also discussed.
