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 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.)
Type of transformers used in gas insulated substation?
Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.
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
What should be the minimum recommended value of power factor of a substation?
A substation is not a load but is a place where switching and voltage-level changing takes place. Accordingly, you cannot apply a 'power factor' to a substation.
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.
What type of gas is used in a gas insulated substation?
sulphur hexa-fluouride
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.

Why sulfur hexaflouride is used in Gas Insulated Substation?
SF6 is used in circuit breakers to help extinguish the arc when deenergizing parts of the system. It is a dense inert gas that will deionize the are.
What is the advantages and disadvantages of substation busbar?
There are no particular disadvantages for busbars, other than they must be insulated and occupy space, but as busbars are essential, then this is to be expected.
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
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 a mini-substation?
A substation that is smaller than the average substation. A substation converts electric power from one voltage to another.
What is pooling substation?
The Substation which comes power from the power plant know as pooling substation.
