Spittal Substation - SSEN Transmission

The project at Spittal consists of a 132/275 GIS AC Substation and a 800 MW HVDC Converter station. A design and build contract for the AC the Substation was awarded to an ABB/Balfour Beatty consortium and a separate design and build contract for the DC HVDC Converter station to ABB. The AC substation is due for completion Q4 2017 with the HVDC in 2018 in line with the overall Caithness-Moray project.Get price

SSEN Transmission’s sites lead the way with use of new

Fort Augustus is the first substation using both 145kV g 3 switchgear and 420 kV g 3 gas-insulated busbar. New Deer is the longest 420 kV g 3 GIB ordered to date. Using g 3 instead of SF 6 in those two substations will avoid the installation of approx. 200,000 tons of CO 2 equivalent. That’s equal to removing 43,500 passenger vehicles fromGet price

Effective and Safe Testing of GIS Switchgear - Electricity

Gas-insulated switchgear (GIS) in particular poses unique and special challenges, including the connection of the test equipment. In today‘s world, where testing is increasingly performed in a non-invasive manner, test systems must offer a certain flexibility and a wide range of testing solutions in order to get proper results in a timely manner.Get price

Gas-insulated Switchgear (GIS) Testing - OMICRON

Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (Sulfr hexafluoride) gas. A perfect condition of the insulation is essential for ensuring a reliable operation of GIS. The characteristics of the sf 6 gas also allow the extinction of arcs which can occur during disconnection of live contacts.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 sf 6 can do in centimeters.Get price
