We could also run multiple 75kVA transformers located in the factory
layout, where they showed the red boxes.  This might be better for the
electrical lines to run 480V to the transformers located next to the
equipment and run shorter power lines for less power loss.   There is a 5th
transformer that would need to be used for the individual welders.   For 5
transformers that would come in around $31,360.  I was also hoping that we
could negotiate volume pricing and save on sales tax with our exemption
certificate.

Running two 225kva transformers would come in around $30,566.

I would pay the $794 for the benefit of not having power loss in the lines
going to the equipment.   Just a thought.
