Gas-insulated switch SF6 газ density monitor

2. Description of the Related Art In a gas-insulated switchgear, in order to maintain a constant dielectric strength, gas pressure in the container is measured to detect gas leakage. However, the dielectric strength of SF6 gas in the gas insulated switchgear is maintained not by the pressure of the gas but by the gas density.
