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

During Testing of Maintenance Free Earthing, How deep should be the Spikes of Earth Test Meter should be inserted in the soil(one spike is 15 Meter & Other spike is 30 Mtrs away from the Main Earth Electrode. Because, recently, we observed that when spike is inserted 3-4 Inch in the earth- results are better, If spike is inserted 1 feet deep than results are increasing.
