Follwing series of action will occur when 100Hz power is
applied to 50Hz transformer.
1) Core gets saturated
2) No,load losses increases and Temp. too goes up
3) Output voltage cannot be predicted as the core is
totally saturated.
4) Heating continous and gradually damages the core
5) This is followed by heating up of the oil and thus
cooling temperature goes down sharply.
