Answer / arb555

The reason is some thing 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. This is the reason. It has nothing to do with
form factor (1.11). Nowadays that thought has changed and we
are using 400 V instead of 440 V, or 230 V instead of 220 V.

IT HAS NOTHING TO DO WITH FORM FACTOR 1.11
OR
TRANSFORMER EQUATION 4.44*f*fi * smting

Answer / psychoelectric

It's just a myth. . . have you ever seen 220v line,it doesn't even exist. The transmission line are usually of 230v and for high voltages we use 400kv power system.

Answer / raja

it is in no way related to the form factor. this is a misconception.
the way the parameters today seem to be multiples of 11 dates back to 1900...1910... dc vs ac....edison vs tesla(not the car)
NOTHING TO DO WITH FORM FACTOR
pls google war of currents ....there is a good wiki page and there are multiple video documentaries on youtube related to this......
