Abstract :
In this paper, the voltage-sharing performance of MOA (metal-oxide surge arrester) for 1000 kV UHV GIS is discussed using the secondary development of the finite element and boundary element numerical method by 3D simulation, ensuring the non-uniform rate of the voltage distribution can be controlled within 10%, reaches the requirements of electric field distribution and the voltage distribution on the resistors for the ultra-high voltage project. In the end, the reasonable configuration parameter of grading ring of tank type MOA for ultra-high voltage GIS is provided.
