  • SF6 Leak Rates from High Voltage Circuit Breakers - U.S

    gas carts, which are used to remove, store, clean, and re-fill SF6gas to high-voltage equipment, are considered a major source of handling-related losses. Equipment leakage, on the other hand, is the result of the deterioration of SF6-containing equipment fittings and materials with time and use through chemical, hardening, and corrosion effects.
