Major components you can spot while looking at HV/EHV GIS

Busbar. The busbar is one of the most elementary components of the GIS system. Co-axial busbars are common in isolated-phase GIS as this configuration results in an optimal stress distribution. Disconnectors. Disconnectors (or disconnect switches) are placed in series with the circuit breaker to provide additional protection and physical isolation. Circuit breaker. The circuit breaker is the most critical part of a gas insulated substation system. The circuit breaker in a gas insulated system is metal-clad and utilises sf 6 gas, both for insulation and fault interruption. Current transformer. The conventional substations use either live-tank or dead-tank type current transformers with oil/sf 6 insulation. A porcelain insulator is used to insulate the low potential section of the current transformer from the high voltage zone. People also askGet price

The four most common switchgear-based substation types | EEP

Open Air SubstationsMetal EnclosedMetal-CladGas-Insulated SubstationsOpen air substations contain separately mounted and interconnected switching equipment and components, like current transformers (CTs), voltage transformers (VTs), busbar support insulators, cable sealing ends, etc., where atmospheric air provides the main insulation path to earth. This is very important requirement and it requires relatively large clearancesand, in consequence, open-air substations tend to cover large ground areas. Also, if substation is located near local communities, they’re usually not very happy about its location. Some degree of landscaping is normally required to minimize the visual impact.

Electrical substation - Wikipedia

Transmission substations can range from simple to complex. A small "switching station" may be little more than a bus plus some circuit breakers.The largest transmission substations can cover a large area (several acres/hectares) with multiple voltage levels, many circuit breakers, and a large amount of protection and control equipment (voltage and current transformers, relays and SCADA systems).Get price
