Abstract
In this paper, short line fault breaking performance of SF6 gas circuit breaker was evaluated by calculating the post arc current and the temperature on arc axis. For the analysis of arc-gas flow, finite volume fluid in cell method was used to solve governing equations. In arc modeling, finite element method and the method of partial characteristics were used for the calculation of Joule heating and radiation model, respectively. Also, the effect of ablated nozzle vapor was considered in the simulation. The calculated results were compared and confirmed with the experimental values.
