Evaluation of high-voltage circuit breaker performance with a validated arc model. N2 - A digital current-zero measuring system was used to monitor about zero crossings of short-line fault currents in three designs of commercial high-voltage circuit breakers. The breakers were subjected to standard IEC tests in a high-power laboratory. With these results, an empirical arc model was derived, based on the series connection of three classical modified Mayr models.
