what would happen if a Transformer (rated at 110V/60HZ) is connected to 230V/50Hz supply. And vice versa???

Question

plz. note...it's a single phase transformer

Answer 1

if your transformer is rated 110 volts and you connect to 220 volts, either 50 or 60 hertz, then your transformer will go up in smoke, period.
if your transformer is rated 220 v, 50 hz and you connect to 110 volts, 60 hz, then the voltage output will be half of the rated one, you can do this, most transformers if not all are rated 50/60 hertz, and the only thing that will change is the volt-ampere of the transformer.

Answer 2

The output voltage would approximately double, and if you are not lucky you will notice a funny smell and a cloud of smoke coming from the transformer if you double the input voltage. If you halve the input voltage you will have the output as well.
I believe that the current through the windings will be slightly higher due to the change in inductive reactance due to change from 60Hz to 50Hz.

Answer 3

110 transformer at 230:
If the insulation stands up to it initially (which it probably will), then the fuse won't blow straight away, but the transformer will slowly become hotter and hotter, until the varnish insulation softens and several of the turns become shorted, after which the heating will accelerate and more turns will become shorted - once a single turn becomes shorted in a power transformer, the transformer is effectively a useless lump of scrap.

230 transformer at 110:
Just a lower output voltage, in the ratio 230:110

The difference in input frequencies will barely make a difference.

Answer 4

1 the out put voltage will also increase in the ratio of 230/110
2 now the current carrying capacity will decrease to the ratio
110/230
3 if you are using induction motors load speed will reduce by
50/60
4 if transformer winding will weak to stand up to 230v it may
burn also

Answer 5

if a low voltage high frequency transformer is connected to ahigh voltage low frequency transforner, the copper losses will remain the same but the core losses will increase.....also as per the equation :volts/turn=4.44 x f x Bm x Ai........so the voltage per turn will also increase.........

Answer 6

The insulation, (generally 600V. Minimum), should withstand the difference in voltage.
The difference in frequency would result in core heating problems.
