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.

The assembly may also contain cabling, buswork with appropriate insulators, current transformers, electromechanical or electronic relays, and metering. Reliable operation of the protective devices is vital to system safety; however, these devices can be adversely affected by water.

Oil regeneration - Hitachi ABB Power Grids reclamation or oil regeneration is a process whereby oil is processed to achieve a significant condition improvement, aimed at being as close to "as new" as possible, by removing the aging products. The processing is performed while a transformer is in service to achieve maximum effectiveness, with minimum impact to site operations.
