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.
When did gas insulated substation installed in India for first time?
the first GIS substation installed in India at pophali (koyana hydro project in Maharashtra in 1992.)
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.
What happens at substations?
At substations, the voltage of electricity is either stepped up or stepped down depending on its application. They serve as an intermediate point between the power generation plants and the consumers' electrical distribution system. Substations also provide various protection and control mechanisms to ensure the reliable and efficient transmission and distribution of electricity.

Advantages of gas insulated substations?
Gas insulated substations do have some advantages. They are preferred in cities and large towns, and are considered to be safe, reliable, and maintenance free.
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.
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.

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.
What is general property of Twisted pair cable?
