Abstract

Accurate high-voltage arc simulation is vital for optimizing circuit breakers, critical for power grid protection. Complex arc phenomena, especially radiative heat transfer, pose significant computational challenges. This paper validates the Equal Emission Banding (EEB) method for efficient radiation transfer in switching arcs. The method balances accuracy and computational time, improving precision without significant overhead. This advancement is expected to aid future research.
