Abstract :
In this paper, the finite element method (FEM) is applied to calculate the unbounded electric field of a 40.SkV vacuum interrupter (VI). During calculating, multi-dielectrics (such as; air, porcelain casing, vacuum) have been taken into consideration, 4nd the potential variations of each floating electrode under different operating instants hare been obtained. Moreover, the whole electric field distributions of the VI with different opening strokes have been computed and figured out dynamically.
