Communication Numerical Computation of Potential Distribution along a Transmission Line Insulator Chain

A combination of the integral equation method and the charge simulation technique has been used to compute the potential distribution along a HV transmission line insulator chain taking into account the influence of tower, crossarm, conductor, and ground. It is shown that the environmental influence is marked at the line end unit. The relative influence of crossarm and conductor on the potential distribution is discussed. It is shown that the crossarm has a greater influence on the potential distribution than the line conductors.
