Abstract

The electric field and potential distributions in the vicinity of non-ceramic insulators under dry and clean conditions are presented. A three-dimensional electric field analysis program, COULOMB, has been used for the calculations. A three-phase 765 kV power line tower geometry is considered for the potential distribution calculations along the insulators. For three-phase energization, two-dimensional contours of the three-dimensional equipotential surfaces are presented in selected vertical planes. The effects of the presence of power line conductors and of the three phase vs. single phase energization on the electric field and potential distributions have been investigated
