Abstract
The electric fields in the arc-extinguishing chambers of the puffer SF6 circuit breakers were calculated using a quardrangle 8-nodded isoparametric Finite Element Method. The influences of the arc chamber structrue on electric field were discussed by analyzing the numerical results of 100% gap distance. Two different arc chamber structrues were compared
one of them was modified to overcome its shortcomings.
