Because of that the pressure of the gas inside the extinguisher chamber decreases. The arc quenching capability of the breaker may deteriorates if pressure of the gas decreases. So to avoid this, regular checking of a SF6 CB, for SF6 leakage is quite necessary.Maintenance of SF6 Circuit Breaker - About Circuit
