Why electricity in India is in the multiples of 11 like 11kv, 22kv, 33kv?
Transformer Induced voltage equation contains 4.44 factor.
E=4.44*f*T*phi E -Induced emf per phase T -number of turns f -frequency phi -maximum flux per pole From the equation we see that E is proportional to 4.4 and it is in turn multiple of 11.
