Connection Types - Welcome to National Grid Group | National

A GIS bay differs to an AIS one as the circuit breaker and isolator are part of the bay, therefore there is a different ownership regime at these substations. Please enquire through the Research Assistant for this or any other options and we will setup a pre-application discussion to explain all the options available to you.Get price

Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, sf6 gas, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in Sulfr hexafluoride gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what Sulfr hexafluoride can do in centimeters.Get price

Final distribution substations - EMFs

This does happen but is relatively rare in the UK. The design of substations varies. The individual items of equipment in outdoor substations tend to be relatively compact, and modern substations are often a "unit" design where the transformer, switchgear and fuseboard are all bolted together in a single unit, which is even more compact.Get price
