Answer / sudhanva

The form factor of an alternating current waveform (signal)
is the ratio of the RMS (Root Mean Square) value to the average value (mathematical mean of absolute values of all points on the waveform). In case of a sinusoidal wave, the form factor is approximately 1.11.
The reason is something historical. In olden days when the electricity becomes popular, the people had a misconception that in the transmission line there would be a voltage loss of around 10%. So in order to get 100 at the load point they started sending 110 from supply side. Now a days when, we have voltage correction systems, power factor improving capacitors, which can boost/correct voltage to desired level, we are using the exact voltages like 400KV in spite of 444KV...

Answer / piyush pandey

as we know that the emf which is genereted from the alternator
have the quantity which is multiple of 1.11,Actually available voltage/phase is E = 4.44KcKdfTф.Therefore in india we have generating voltages 220kv,440kv,11kv.
