Abstract
The principal object of this paper is to provide a comprehensive approach for parallel processing of potential and electric field calculations. The approach investigated under dry and wet conditions for two types of insulators, the ceramic cap and pin and the polymeric, in three different high voltages: 230 kV, 400 kV, and 765 kV account for the two design factors: towers and bundled conductors. Moreover, corona is an important phenomenon associated with all transmission lines that causes the surrounding air molecules to ionize, or undergo a slight localized change of electric charge. As such, the effects of the corona rings on the insulators considering potential and electric field distribution are other objects of this paper. Decisively, this requires accurate and efficient modeling of the proposed insulators on the tower conductors of the transmission lines which is derived by a detailed localized potential and electric field distribution approach that combines the different aspects of the transmission high voltages. The corona rings' optimization for six individual insulators is another object of this study.
