Hybrid finite element-charge simulation method for SF/sub 6/ tank type circuit breaker with double breaks analysis

The electric field simulation for the axisymmetric configuration of the SF/sub 6/ tank type circuit breaker is proposed based on the domain decomposition method in this paper. The mathematical model is based on coupling finite element method (FEM) and charge simulation method (CSM). It is shown that the hybrid FEM-CSM is capable in calculating the complex open boundary problem, demonstrating the great potential of the hybrid method in different fields.
