Installing 50 Hz 200 KVA 3 KV transformer in 60 Hz system

If the transformer is designed for 50 Hz, you can use it in 60 Hz system but not the vise-versa.

The induced voltage formula is

V = 4.44 x f x B x A x N

OR

A = V / (4.44 x f x B x N)

Where V = induced voltage, f = frequency, B = flux density, A = Cross sectional area of core and N = Number of turns

The cross sectional area of the transformer core is 20% bigger for 50 Hz than 60 Hz. So, in terms of flux saturation, it should not be problem but the transformer % impedance (or voltage impedance) will be 20% more than the one you find from nameplate, because impedance is directly proportional to frequency (X = 2 x PI x f x L). If the increase of 20% impedance is not a problem for your system (for increase voltage drop or voltage regulation), you can use it.

Dear Mr. Msamad Sir,

With reference to your answer for the above question, i had a doubt which i wanted to have a clear clarity. I have observed static electrical machines like transformers and chokes, reactors emit sound . From my fundamental knowledge of electrical engineering, i came to know that the sound was because of effect called magneto-striction. further to this information, i came to know that since the laminations cannot be ideally 100% mechanically stacked, the noise emits due to individual lamination vibration and also due to inter-lamination vibration. I request yourself to give me a bit more practical information regarding this matter.

All our esteemed forum members are also requested to give their expert advice.

Thanks

Losses and induced voltage will be more. It will cause damage to insulating material. proper cooling arrangement should be done.
