EN - European Commissionec.europa.eu/competition/antitrust/cases/dec_docs/...· PDF fileThe function of switchgear is to protect the transformer from overload and/or insulate the circuit and the faulted transformer. (7) Insulation of switchgear may be through gas, air or some combination of the two ('hybrid switchgear'). Therefore, to a limited degree, GIS faces competition from air-insulated switchgear (AIS) and hybrid ...
