Oil regeneration some transformers, there is data available for up to 10 years after reclamation. The data shows very little change in acidity and color after 10 years in operation since the oil was reclaimed. To prevent excessive production of acids due to oil degradation, it is recommended that the oil be reclaimed before it is severely degraded.

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.
