Abstract
The electric field is one of the main factors which causes the corona discharge and insulation defect of high voltage insulators. Therefore, the voltage distribution and electric field calculations along the insulators is important for the design and development of transmission lines. Depending on the construction position, suspension insulators are connected at a certain angle to the vertical line. This is called insulator string deviation. The insulator string deviation can change the electric field distribution of the insulator string. In this paper, the insulator string offset effect on the electric field distribution of a 230 kV suspension insulator string has been simulated. The insulator string has been simulated in COMSOL software based on the finite element method. The effects of 15 and 30-degree insulator string deviations on the electric field distribution, the insulator string efficiency, and the effective length of the insulator string, have been investigated. Then, the results have been compared with the insulator string without the offset. The simulation results show the significant effect of the insulator string deviation on the electric field and voltage distribution of the insulator string. Also, the effect of insulator string deviation on the effective length of the string and its dielectric strength is significant.
