Electric Field Analysis

Using the finite element analysis, this work analyzed the electric field distribution of 220kV transmission steel tower with double-circuit and composite material transmission tower with the same size, and compared the electric field effect of two materials transmission tower for surroundings. And this work compared the vertical and axial electric field distribution along transmission line of the two materials transmission tower. The results indicate the composite material tower can improve the environment of electric field near the transmission lines.

Insulation Performance

The performance of insulator strings in transmission lines can be improved by corona rings owing to their electric field grading property. The insulation performance of the string depends on the corona ring parameter settings. In this study, the design of a corona ring for a 400 kV non-ceramic overhead line insulator is presented. Two parameters were altered during the investigation, ring measurement (R) and ring tube breadth (r) while maintaining a constant ring height (h). Based on electric field distribution, the proposed composite insulators were compared with glass insulators. Simulation studies were performed for the insulator strings, including corona rings with different design parameters. The corona discharge and optimal configuration results were analyzed, and it was found that the electric field was lower with composite insulators.
