What is the Difference between air insulated substation and gas insulated substation?

Air insulated substation means air acts as the dielectric medium but in case of gas insulated substation SF6 is the dielectric medium. Gas insulated substations are having more advantages than air insulated substations.

Where are gas insulated substations to be installed?

gas insulated substations are installed especially where floor area available is limited and maintenance cost is more

Existing location of gas insulated substations in India?

There are 230kv and 110kv GIS substations in chennai functioning from 1998 ,commssioned by Tamilnadu electricity board.

What is the concept of Gas insulated substation?

Gas insulated substations are in use in places where a normal, above ground substation would constitute an eye sore for the community. A gas (SF6) insulated substation may have underground feed lines and be nearly invisible to the average person -- except for the location where the transmission feed wires go underground from the transmission towers. distribution circuits supplied by gas insulated substations normally have an alternate feed from another substation, to allow maintenance work on the gas insulated site.

What is the Difference between air insulated substation and gas substation?

Air insulated means the substation is in the open air, and the dielectric strength of the air is used to isolate conductors from each other and from ground. Gas insulated means a specific gas is used for insulation; this gas is usually an inert gas such as nitrogen. Gas insulated substations, by definition, are required to be inside a contained structure, or large piping must be placed around all conductors to hold the gas.

What type of gas is used in a gas insulated substation?

sulphur hexa-fluouride

What are the advantages of wired?

It protects the insulated conductors against mechanical and environmental damage.

What are advantages of gas insulated sub station?

it requires lesser space compare to normal. design of switch gear is more compact , has the potentials to increase system reliability and has less maintenance and longer service life.

How a gas insulated substation works?

This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask for the answer. Earn your diploma.

Insulated windows life expectancy?

There are different types of insulated windows, and they can all have the same life expectancy as a normal single pane window when no damage is caused to them. Many of the better insulated windows have the following structure: pane of glass; gas, film, gas, and another pane of glass. This sits in a frame with a seal. The biggest problem for insulated windows is that the seal breaks letting the gas escape, reducing the effectiveness of the window. This seal can break with damage to the frame.
