office spaces that have added floors of computers are faced with
upgrading the buildings' distribution transformers. The design type
for this situation is called a "high K factor" rated transformer, and
you pay a premium for this type. It's only in the past ten years or
so that the problem has been truly recognized.

Tony is right about K-rated transformers. And now, there's another
good option: Harmonic Mitigating Transformers. For more on this, see
my article "New Power Tools" posted in the files area of this forum.
