Does anyone have any recommendations on whole house electrical conversion from 127 volt 50 hertz to 120/60. I understand some people have done this.

I know of houses that have been converted from 127V to 120/115V 50 Hz. This was done using transformers.

Just for grins, I did a quick Google search for frequency conversion. At http://www.elect-spec.com/freqchgr_a.htm#B you can convert 230V/50Hz to 115V/60Hz. These conversion units appear to accept a +- 20% input voltage variation which should handle Bonaire's voltage. Anyway, a 250VA unit costs about $2,000 and a 5,000VA unit costs $13,635. At full load the efficiency factor is 78% minimum, so you should add about 20% to the already high cost of electricity if one installed this solution.

It can be done. The reason that the frequency converters are so inefficient is that they are basically a 50Hz motor driving a 60Hz generator. There are solid state ones, too, but they don't generate a sine wave, they generate a square wave. That will hurt your motor worse than Bonaire power.

I have only used a transformer for my fridge and washing machine for the past 20 years. Knock on wood, only lost one microwave over the years. I Agree with Kevin. The only thing I do at home and at the shop is to use line conditioners on my computes which evens out the power dips.

I just installed a new us made microwave and it does not work?? It is on a transformer, it will only stay on if you keep your finger on the start button. When you take it off, it stops?? Any suggestions?

Did you buy the microwave on Bonaire? I bought a Sharp on Bonaire (120v, 60Hz) model and with a transformer it worked fine.

I had it shipped from the states, it's a whirlpool. I had the maintenance guy at or condo complex install the transformer and hook up the electrical, so I don't know the size. I'll send them a note to check the voltage and transformer size!
