sf6 switchgear monitoringsolutions for 220kv

The switchgear is composed of isolators that open/close and cut off circuits of current, disconnectors that electrically isolate circuits and open voltage, and other components. Gas Insulated Switchgear (GIS) is the name for a unit that houses these components and circuits in a single gas tank with a compact footprint.
