What are the components of air insulated substation?
AIS primary substation equipment contains of a portfolio up to 1100 kV including live tank circuit breakers (LTB), dead tank circuit breakers (DTB), instrument transformers, disconnectors, surge arresters, monitoring and controlled switching..
What are the components of AIS substation?
AIS, or Air Insulated Switchgear, is a type of electrical substation equipment that uses air as the primary insulating medium.
It consists of various components such as circuit breakers, disconnect switches, and busbars, which are arranged in open-air compartments..
What is air insulated substations?
An Air Insulated Substation (AIS), commonly known as an Outdoor Substation, has all bus-bars, switchgear components, and all other switchyard equipment installed outside, unlike their indoor counterparts that have the apparatus installed within the building of the substation..
What is an AIS substation?
AIS: Stands for an Air Insulated Substation.
An AIS or outdoor substation insulates the main circuit potential from the ground by air using porcelain or composite insulators and/or electrical bushings.
The AIS arrangement is ideal for low voltage rating substations and substations with ample space..
What is the difference between GIS and AIS?
Each type of switchgear's longevity and maintenance depend on how it was built.
While AIS insulates using air in a metal-clad structure, GIS uses the chemical gas sulfur hexafluoride.
Since it is five times heavier than air, sulfur hexafluoride exhibits excellent extinction behavior..
What is the difference between GIS and AIS?
In summary, AIS uses air as the insulating medium, while GIS uses specialized insulating gases.
AIS tends to have larger physical dimensions and requires more spacing between components, whereas GIS offers compact designs with reduced maintenance requirements..
- Gas insulated substation (GIS) consist of components where active parts on high voltage potential are located in the middle of the aluminium alloy pipes and held in this location by epoxide resin insulators.
- Its function is to step-down or “transform” high voltage from the power transmission lines to a lower voltage that can be sent out through the distribution lines for power supply into homes and businesses.
