how we can know the rating of transmission line by no. of insulators disk ??????????..

Answer / palla suribabu

we know that each insulator disk can tolerate upto 11kv,for example when we want to find no. of 220kv,first find phase voltage for 220kv and then divided by 11kv.

phase voltage=220/1.732=127kv
no. of discs=127/11=12.
according to economic and safety are taken into account,it value varies from 11-13 discs.

Answer / mitesh patel

The 400 kv transmission line required no of disc ppt the value this formula
Value of voltage (KV)
N = KV/19.03
Then add 1 disc . Fore exmalpe
400/19.03 = 21.01~ 21 + 1 = 22 disc required
