Numerical Computation of Lightning Induced Surges on Overhead Power Distribution Lines

S. M. Abdur Razzak, M. Abdur Rashid, M. Z. I. Sarkar, Shiro Tamaki and M. Mortuza Ali

Abstract—This paper presents numerical computation of lightning induced surges on a overhead power conductor taking into account real earth conductivity. A modified dipole technique is used to compute lightning generated electromagnetic fields radiated from lightning return strokes. A modified Agrawal transmission line model is used to calculate interaction between the electromagnetic fields and the overhead power conductor based on the finite difference method. Induced overvoltage waveforms resulting in from a front return stroke current model are presented for different line heights. Validity of the new dipole technique as well as the modified Agrawal model is also tested.

Index Terms—lightning induced surge, electromagnetic compatibility, finite difference computation, overvoltage phenomenon, and computational electro-magnetics.
