End of life estimation of HV switchgear and GIS substations

Jun 10, 2016 · GIS is characterised by high service reliability, low maintenance expenditure and long lifetimes. GIS technology requires more investment costs compared to air-insulated substations (AIS), however, due to its space saving features, this technology often offers the only solution where available space is limited.Get price

Tracking the pros cons of air and gas substations - ESI Africa

Jun 28, 2018 · Tracking the pros cons of air and gas substations. Taking into consideration that the cost of a GIS indoor substation is much higher compared to an AIS substation, it’s handy to have a quick reference guide to the pros and cons of both indoor and outdoor substations, writes John Greyling, switchgear specialist and Director of Hevilex, South Africa.Get price

Gas insulated power transformers: A growing technology - EE

Mar 12, 2018 · Most power transformers use oil as an insulating and cooling medium but, where substations are located in restricted spaces, gas is used for this purpose. Gas insulated switchgear is commonly used in substations and the development of gas insulated transformers allows complete integration of substation equipment with resultant space and cost savings. Gas insulated transformers […]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
