wat is the advantage of increse in frequency?how the
powersupply range decreses as the frequency increses?like
in america,it uses 110 ac and 60 hz?

Answer / krishna sai
with the increase in the frequency by keeping the kva rating of the machine constant then the size of the machine can be reduced.
on the other hand during the design stage if the frequency is increased then the KVA rating of the machine will be increased as KVA proportional to EI where E(induced voltage) is proportional to f. Power supply voltage range must be decreased along with the increase in frequency so that the machine will be safe without getting into saturation

Answer / kj
One advantage is that as the frequency is increased less
iron is used in a generator or motor. Between 50 and 60 Hz
there is only a slight difference.
Where there is a major difference is when the frequency is
increased to 400Hz. This significantly reduces the weight
which is critical in aircraft where this frequency is used.
