SF6 room sensor module for HV MV

SF6 room sensor module for HV MV

Oct 26, 2018Vacuum switching widely used in the medium voltage range, is also emerging as an alternative in HV applications. This trend is being driven by the fact that the vacuum switchgear is more environment friendly than SF6 switchgear. Hybrid switchgear is a combination of conventional air insulated switchgear and high voltage gas insulated switchgear.
