摘要：

Simulation of the electric field and potential distribution is widely performed in the design of high voltage composite insulators. This paper introduces and analysis of electric field distribution around the insulator under a 22kV high voltage AC (HVAC) transmission line. A two-dimensional model is built to calculate the electric field distribution in single phase system and another 2-D model is used to calculate the distribution under a three-phase HVAC transmission line. The effects of the metal ground pin are considered in the model and a comparison of the single phase system and three-phase system is given in the conclusion. The results show that electric field strength in a three-phase system is significant larger than a single phase system. The electric field fluxes are also affected by the ground pin and other two phases in a three-phase system.
