why transformer is giving some humming noise .....?

Answer Posted / abid ali khattak

due to the eddy current losses. Because whenever we provide
the power supply to the transformer emmidiatly flux run in
the core.hence due to the silicone immitted core the
insulation between one layer to another layer is becomes
lettle and the fulx will go high which is becomes vibration
and giving the noise. Which we can observed nearby the
transformer.
