I found something I read rather a while back on HV electric motors. This is a
Marine Accident Investigation Board report on an 11KV Harmonic Filter in the
power supply to the Queen Mary II.

It appears that the QM2 motors run on 1.5 KV, though power through the filter
is 11 KV. I distinctly remember the CHENG on the Triumph telling me that the
motors ran on 17 KV AC, but suspect that he meant that that was what came out
of the VFD and through the harmonic filters, and that the pod motors ran on
something like 1.5 KV. 

We're talking about boats -- OK, ships -- and BIG motors, which qualify as
boatanchors.

This stuff has to run CCS, not ICAS. It certainly is hefty.
