just read abt form factor....

Answer / shashidhar

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.
So always transmission voltage is multiple of 11

What is the function of RCBO? What are the different sensitivity ratings & each application?
