UHVAC Substation and Main Electrical Equipment - ScienceDirect· In addition to the main electrical connection, the type of switchgear is also a major factor in determining the layout of the substation. Currently, the types of switchgears employed in UHV substations and switching stations include gas insulated switchgear (GIS), hybrid gas insulated switchgear (HGIS), and air insulated switchgear (AIS).
Medium-Voltage Switchgear Doesn't Require SF6 as ... has introduced another medium-voltage switchgear that doesn't require sulfur hexafluoride (SF6) as the insulating gas: the 8DAB 12.The system uses clean air consisting only of the natural constituents of ambient air as the insulating gas. The switchgear is a new addition to the 8DA and 8DB product family and also works with the proven vacuum switching technology.

"We're getting close to where we're actually deploying this ...
Dissolved gas analysis - Wikipedia gas analysis (DGA) is the study of dissolved gases in transformer oil.. Insulating materials within transformers and electrical equipment break down to liberate gases within the unit. The distribution of these gases can be related to the type of electrical fault, and the rate of gas generation can indicate the severity of the fault.
Switchgear - Wikipedia for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.
