Isolation transformer - Wikipedia isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety reasons. Isolation transformers provide galvanic isolation; no conductive path is present between source and load.This isolation is used to protect against electric ...

Switchgear sf6 Treatment plant sf6 Treatment plant. 69th Street Wastewater Treatment Plant - GAI's new design included two new 3750kVA (15kV/4160V) transformers, two new 1000kVA (15kV/480V), three SF6 switches, and new 480V power distribution switchgear with all the conduits, wiring, and terminations to the existing loads within the pump control room.
Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
