ya....this is rajkumarsripelli Testing engineer trasformer
division...
Kaarthikrt&c09894209497 said that due to corona loss is
dead wrong..for 2nd answer
2:ans: the noice will be getting from loaded transfomer is
due to the mechanical vibration of the core...in detail...
for making of transfomer as we know that we will be using
silicon steel core material...so this core is assembled in
proper way..as per the standareds...when we apply the
voltages through the windings to this core the core will be
magnetised...due to this high voltages the core will
vibrates when its magnetised....and the vasavi said above
may be correct...........
thanks..
