It has been observed in our tests that the post arc current near the breaking limit of a CO<sub>2</sub> circuit breaker is 10 A or more, and the post arc current of a SF<sub>6</sub> circuit breaker is approximately 0.3 A. We explain this major difference in the post arc current with calculations using two serially-connected arc models. We prove that the arc(More)
