WHY ARE ALL THE VALUES OF VOLTAGES OF TRANSMISSIONS ARE IN MULTIPLES OF 11, MEANS 11KV, 33KV, 110KV, 220KV.? MY TEACHER ASKED US THIS QUESTION. PLZ HELP.

why the transformers in transmission step up/down at the voltages which are multiples of 11..,like 33kv,66kv,121kv,etc?

its been a convention from olden days... there is no specific reason to it...
@Sparker • 10 Jan, 2013 • 1 like
its not that it must be multiple of 11. Actually in olden day the used the multiple 1.1 i.e. formfactor for sine wave ,so that computation will be easier on design.its not 11 ,its 1.1 and its not compulsory.Infact not UHV,HVDC are not multiples of 1.1 .

certainly thanks a lot frnds who have replied me with the apt answers😀😀..............

Nice to see your active involvement here. But a little of topic It will be even more better If you can avoid SMS language here in the forumssree_23certainly thanks a lot frnds who have replied me with the apt answers😀😀..............

depends on the form factor .... for a.c its 1.11KARAD123WHY ARE ALL THE VALUES OF VOLTAGES OF TRANSMISSIONS ARE IN MULTIPLES OF 11, MEANS 11KV, 33KV, 110KV, 220KV.? MY TEACHER ASKED US THIS QUESTION. PLZ HELP.

@Akhilesh Garud • 15 Jan, 2013
is there any exact relation of its dependency on form factor?ani the legenddepends on the form factor .... for a.c its 1.11
@eris • 15 Jan, 2013
I hope it s dependent on RMS value n form factor. . Both r directly proportional to each other
@m.b • 02 Mar, 2013
please frnds try to answer it as I have been lukng for it for a long ago
@mallumatmari • 11 Mar, 2013
Only extra high voltage systems(super grids) have voltages in multiples of 11. I think because those transformers have 1:11 or 11:1 ratio. Simply guessed, don't know anything about that.

@shiv786 • 21 Mar, 2013
form facto is rms value upon avg. value
and value of form factor is 1.11 for transmission
so in my opinion that's the reason.....

it is due to form factor
