SF6 Breakers Components Detection for Hitachi

SF6 Breakers Components Detection for Hitachi

It is the first time that clean air has been used instead of SF6 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 SF6 which has traditionally been the method of insulation in high voltage switchgear since the
