[Milsurplus] Question...

[Kenneth G. Gordon]

At this point, I don't know where else to post this, so here goes:

I have a "small emergency generator", 7500 watts, brand new.

>From my reading, I find that the output waveform is very "dirty" as it is some sort of "stepped" 
square-wave. I have not yet looked at the wave-form with an oscilloscope, but I am not 
expecting it to be very pretty.

My old military generators output a nearly pure sine wave, but these modern beasts don't.

SO....I have two heavy (about 70 lbs each) 115-115 volt isolation transformers. good for at 
least 15 amps input/output each.

I propose to "tune" them to 60 Hz by connecting capacitors in such a way as to make them 
into 60 Hz tuned circuits with the idea that doing so should "round off" the waveforms and 
eliminate the harmonics.

What does the collective wisdom think of this idea? Has anyone tried this? What was your 
result?
