Novel Hybrid Method for Computing Electric Field of SF6 Circuit Breaker
The electric field of a SF6 circuit breaker is computed based on the hybrid method of finite element method (FEM) and charge simulation method (CSM), taking the axisymmetric configuration into consideration. It is verified that the hybrid FEM-CSM is capable in calculating the complex open boundary problems, and the calculation results are of higher precision than those of the traditional FEM or CSM, respectively.
