Why transmission voltages are multiples of 11?
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.

Do post your thoughts 😀 -
sree_23why the transformers in transmission step up/down at the voltages which are multiples of 11..,like 33kv,66kv,121kv,etc?

pinankits been a convention from olden days... there is no specific reason to it...
-
Sparkerits 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 .

sree_23certainly 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😀😀.............. -
ani the legend
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. -
sree_23oh yeah i accept what you say....., i'll do so😀.....

is there any exact relation of its dependency on form factor?ani the legenddepends on the form factor .... for a.c its 1.11 -
erisI hope it s dependent on RMS value n form factor. . Both r directly proportional to each other
-
m.bplease frnds try to answer it as I have been lukng for it for a long ago

mallumatmariOnly 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.

Jeffrey ArulrajHey Big guy Why not pinning this thread here That would solve the extra load you guys already have Do so man

shiv786form 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..... -
n.rajeev sharmait is due to form factor
