110 Volt, 60 hz system havin the major advantantage of
safety. 110 volt shoch is not dangerous for human.
But the disadvantage is, it requires more conductor as for
same power current is increased.

in 230 Volt system, electrical shock is dangerous for human
but it saves the conductor for same power.

Answer / ashwin

110/60 system have low looses as compaare to 230/50
calculation is derived fron trf core and iron lossses

is synchrnous pannel is need for two eqal rating transformers to run in parallel
