How does frequency affect KVA rating of a transformer?
If a 500 kva, 400 v, 60 hz t/f is to be operated on 50 hz
frequency then how will its KVA rating change?
a-increase
b-decrease
c-remains same
Also explain why do u think like that.

The transformer EMF relation shows that the EMF induced in the secondary or the primary side of a transformer is directly proportional to the product of the flux (Φm) and the frequency. This also means that the flux is proportional to EMF over frequency.
As an example, for the 500V to 250V transformer, the kVA rating under 60Hz transformer will be smaller than 50Hz. 500/60 = V/50. V has to be smaller to keep consistency.
