What makes the difference between 50Hz supply and 60Hz
supply which one is economical? What is the use of using
increased frequency?
Answer Posted / chandru
When we increase the level of frequency, level of power
losses will automatically reduce.As we are aware of
transformer emf equation, E=4.44fNAB.
f=frequency,A=area of cross-section,B=magnetic flux density
when we increase the frequency, by having E&B as
constant,area of cross-section will reduce.So,the size of
transformer can be reduced with higher frequency
