Abstract：There exists large-scale numerical computation in electromagnetic field which will turn to parallel computation in practical engineering application. Non-overlapping domain decomposition method (DDM) which is suitable of parallel computation is illustrated first in this paper. The formation of element stiff matrix and the solution of the system of linear equations of finite element method (FEM) are all parallelized based on the non-overlapping DDM. So, it improves the parallel degree further than the traditional solution which only parallelizes the system of linear equations. For more accurate computation the potential distribution and the electric field intensity on the surface of hardware fittings, the 3D FEM model of 500kV high voltage transmission line is built and decomposed into 2～6 sub-domains for parallel computation on cluster of 6 workstations in the laboratory. The speedups reveal that parallel computation is superior of improving computational efficiency. The results can be used as the basis to optimize the rings’ location and reduce the electric field intensity of the insulator string high voltage end.
