Answer / amir rashid chishti
If we increase the frequency then transformer size will
reduce so it will not increase. In electronics circuits we
often see very small transformers due to high frequency
whereas in power systems we have large size transformers
due to low frequency.
Hope answered the question!

It will reduce as less flux is required to build the same back emf which is equal to 4.44 x flux x frequency x turns

There is air in a room . the top and bottom of the room are at constant temp. T1 and T2. DRAW THE temp profiles if a. T1 greater than T2 b. T1 less than T2
What happen if we give resistance to the armatuure of a dc motor?a
how the transformer stables out zone faults? Because we use non directional O/C relays .Is there any special considerations are taking into account to overtake this?
In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
