why we use to transmit the power in three phases intead of
single phase ?

Answer Posted / guest

The power generation in india is 11kV 3phase,50Hz & vch is
economical (as per standard)
After genration v have different voltage levels for
consumers(Transmission to Distribution).
in distribution the voltage is steepped down to 440v
because different loads r there for domestic and industrial
needs.
so v can take tappings for any phase for consumers..
