    Some older low-pressure Sulfr hexafluoride breakers employed a pump to provide the high pressure Sulfr hexafluoride gas for arc interruption. Gas circuit breakers typically operate at pressures between six and seven atmospheres. The dielectric strength of sf 6 gas reduces significantly at lower pressures, normally as a result of lower ambient temperatures. Monitoring of the

    It is the first time that clean air has been used instead of sf 6 to insulate 145kV circuit breakers in the UK. It uses a gas mix similar to the air we breathe, made up of nitrogen (80%) and oxygen (20%), as a carbon free alternative to sf 6 which has traditionally been the method of insulation in high voltage switchgear since the 1960s.
