What happens if a transformer with a rated frequency of 50HZ rises to 60HZ？

When a transformer with a rated frequency of 50HZ rises to 60HZ, the following parameters are affected: 

1.Load loss Load loss includes resistance loss, additional loss, etc. The resistance loss has nothing to do with frequency, and the additional loss Pf is proportional to the square of the frequency. In general, the resistance loss Pr accounts for about 70% of the load loss, so the load loss increases to P't=70%Pr+1.44*30%Pf=112%Pt. That is, the load loss is about 1.12 times the original

2. No-load loss In engineering, the no-load loss of a transformer: = So when is unchanged, the no-load loss is proportional to the 1.3 power of the frequency. When the voltage is constant, the magnetic density B is inversely proportional to the frequency f. Bring it into to get = =K So when connected to a 60Hz power supply, the magnetic density is reduced, and the no-load loss is =0.88 times of the original. The load loss of conventional products is 3-8 times the no-load loss. As the frequency increases, the total loss increases.
