ABSTRACT
Porcelain string insulators are extensively utilized in high voltage transmission lines. However, the electric field and potential distribution along an insulator string owing to the existence of metal conjunctions and resulting stray capacitances is not uniform and the units near to energized end fitting are more highly stressed. One practical way to improve the voltage distribution is corona ring installation at the energized side. Thus the investigation of electric ?eld and potential distribution along insulators, in presence of various corona ring designs, is an effective method to choose the most appropriate one. In this paper 3-D software -based on Finite Element Method- is used to investigate the influences of three different corona ring types, which are more common in Iran 230 kV transmission line, conductor length and also insulator numbers on voltage distribution along 230 kV porcelain insulator string. Eventually, the simulation results will be discussed.
