Imran,
I don't know what your trying to say here.? But I was just trying to address the use of the term "manufacture" that Brett used.? This word is very often used in the context of phase convertors, and often misunderstood and misapplied.? People say things like "don't use the manufactured leg!"? You yourself long maintained that Phase Perfect wasn't "true three phase" because of the way it "manufactures" the third leg, etc...?
My point was just that, yes, transformers "manufacture", but not in the same way the phase converters "manufacture".? And none of the maligning of phase converter "manufacture" applies to transformer "manufacture".
I've said it many times, and I'll repeat it once again.? Your machine has no idea whatsoever which leg was "manufactured" by the utility, or the pole transformer, or your phase convertor.? The machine only cares about the waveforms.? If you manufacture lousy waveforms (as rotary convertors sometimes do), your machine might be affected.? The Phase Perfect manufacture "perfect" waveforms, and no machine can distinguish it from utility "manufactured" waveforms.
