What is GIS Substation and how it operate? where these type
of substation installed?
Answer Posted / umamahesh
GIS means Gas Insulated Substation or Switch yard.
There are two types of Substations in practical
1.Air Insulated S/s(AIS)
2.Gas Insulated S/s(GIS)
The major difference between the two is Space,Cost and
reliability
AIS is less economical than GIS.But AIS will take more
space than GIS.
In Maintanace point of view,GIS is very easy than AIS.
In modern power stations recommondations on GIS only.

I completed iti in2004 I was worked in A grade contractor can I get c licence
I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
