Substation
The main types of substations are transmission substations, HVDC terminal stations, distribution substations, gas insulated substations (GIS) and generation substations. Substations are subject to regulations and standards. Substations may provide either or both switching and voltage transformation.
The main components of a substation are conductors, insulators, earth grid, AC auxiliary system, DC auxiliary system, protection system, instrument transformers, SCADA system, automation system, communications system, security system, CCTV system, control switch-room, power transformers, auxiliary transformers, voltage regulation, capacitors (shunt and series), reactors, power circuit breakers, circuit switches, air switches, re-closers, fuses, surge arrestors, metal-clad switchgear, foundations, structures, fencing enclosure, landscaping, oily water system and fire system.
