Siemens to provide UK's first SF6 free 145kV vacuum ... uses a gas mix similar to the air we breathe, made up of nitrogen (80%) and oxygen (20%), as a carbon free alternative to SF6 which has traditionally been the method of insulation in high voltage switchgear since the 1960s. The chemical properties of SF6 gas make it ideal for electrical insulation and arc quenching in high-voltage switchgear.
Switchgear - Wikipedia an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply.

Transformers - an overview | ScienceDirect Topics Transformer. Transformers are the most commonly used AC-AC converter device in power systems. But as opposed to power electronic converters, most transformers are uncontrollable, with a fixed conversion ratio. However, the transformer can be used in microgrids for galvanic isolation and to further step-up or step-down the AC voltage.
