Answer / manju

the standard output of 11 kv distribution transformer is 440v for line to line and 230v for line to neutral.

Answer / bahadure.kapil

because in the 3-phase supply line voltages concider.

Answer / ajit

Because we can only mesure the voltage line to line .There
is no instrument to measure L-L-L

Answer / jq

So that you can have a 240V for a single phase system, for
use to most of the house hold appliances available in the
market that we use.
