Comparison Between Vacuum and sf6 gas Circuit Breaker

Aug 29, 2018 · Because of the high conductivity of the arc in the sf 6 gas, the arc energy is low. (arc voltage is between 150 and 200V.) Because of the very low voltage across the metal vapour arc, energy is very low. (Arc voltage is between 50 and 100V.) Contact Erosion: Due to the low energy the contact erosion is small.Get price
