I thought the 10% variation sounded too high also. I have doubts about the POCO here going to any great lengths for customer service, though.
Is there any kind of UPS or other equiptment for 3PH 240 volt maybe around 20 amp where no mater what you put into it (within obvious limits), that it would stabalize voltage and frequency variations?
I have a cut sheet for the new machine and it's outlining dire consequences for problems with the power including electrical noise.
