Modeling of High Voltage Insulator Strings through Finite Element Method

摘要

The computation of electric potential distribution across suspension insulator strings used for high voltage overhead transmission lines is very important from design perspectives. The voltage distribution along insulator string is not uniform that is responsible for deterioration, corona discharge and flashover. In this paper different discs of insulator strings were modeled and simulated through finite element method. The potential field distribution of suspension insulators were investigated and compared for different materials like porcelain, glass and composite (porcelain and glass).
