Abstract: The aim of the paper is to accurately study the electric field and potential distribution across the silicone composite insulator used in high voltage transmission systems. For simulation study, the finite element method based SOLIDWORKS along with EMS software is used. Silicone-composite insulators are being increasingly used for outdoor applications as they have better characteristics than porcelain and glass types. They have better contamination performance due to their hydrophobic surface. They are lighter and possess higher impact strength. Several methods have been developed for the computation of electric fields and potential along an insulator. The electric field and potential distribution around and inside the insulator when it is stressed by power frequency is examined using SOLIDWORKS along with EMS, which is a suite of programs for 2D and 3D electrostatic field analysis. The software package uses the finite element method to solve the partial differential equations that describe the behaviour of the fields. In this paper, the electric field analysis and potential field analysis is carried out for 66kV, 132kV, 220kV and 400kV composite long rod insulators and using corona ring can decrease the electric field stress. The electric field distribution within and around the high voltage insulator is a very important aspect of the design of insulators. The knowledge of the electric field distribution and other electrostatic parameters are useful for detection of defects in the insulators.
