Buying & Installing 60Hz Transformer in an 50Hz grid

I have spent several years overseas and know not everyone has deep pockets.

"adapt, improvise, overcome"... If my butt was in a crack and I had to do something,

I would set up the equipment, contact technical support of each sub-system I had concerns about and ask them what can I expect on 50HZ. When all had been inspected, power it up and see if it runs. Then you'll know for sure. One final comment, not for you, but the flack I'll take. Sometimes you have to get your hands dirty.

Good luck,

why to go for 60 Hertz equipment for installation in 50 Hertz system.

Frequency is a linear component in the equation for turns ratio N,

Therefore, if the frequency changes, so must the voltage.

A Transformer designed for low frequencies can be used at a higher freq, if the input value is not changed then the peak magnetic flux would be less.

If frequency is reduced, voltage must also be reduced. Since peak mutual flux can't increase, the allowable voltage decreases with proportion

12470(50/600)=10391

Secondary is the same since volts per turn are same on primary and secondary

1150(50/60)=958

You probally will not get the V you need.

Hope this helps

Thanks for your comments.

Hastingselectric: Is a good option to go that route, and it is probably the way we will go. Regarding getting my hands dirty, to me there is no other way to learn. So yes, I will be up to my elbows in this thing I will try not to electrocute myself trying to figure it out

Inayat: Well is easy to answer that one, I have limited funds, this equipment is available at a price I can afford. I asked the question to find out if it would be a deal breaker.

T Man: You are THE man . Thanks, you have told me exactly what i want to hear without cluttering the issue with technicalities. Yes, I realise that running at lower Hertz will have an influence on the power. My calculations took into account that I will not have a "good" and "efficient" system, so my assumptions and cost calculations are based to be 75% effective. Thus 958/1150 = 83% well within my calculations.

Looking at previous threads, I am also preparing for a hotter transformer, so my cooling system have to be able to handle that. I might have to put a dedicated cooling fan on the transformer to assist the airflow and thus increase cooling.

So all in all I think that the system can work. I will keep you posted on the results of the installation.

Someone should correct me if I am wrong here.

I think the biggest problem with using a 60 Hz transformer on a 50 Hz system will be overheating of the transformer if attempted to run at the transformer rated primary voltage.

The reason being is that the 60 Hz transformer will not have sufficient iron core (for operation at 50 Hz) to generate the required back emf which will result in excessive primary current being drawn at rated voltage. The transformer primary (and secondary) impedance will be much lower at 50 Hz than at 60 Hz.

50 hz will saturate the core of a 60hz transformer

so if we reduce the frequency you should also decrease the volt of tr to maintain the v/f ratio
