I would hope that they would be on some sort of system that keeps the
voltage constant during the transfer from utility to generator power too.

I thought they had an orange triangle on them? Many of the ones I've seen
are that way. Maybe hospital grade isolated ground receptacles have a
green triangle on them instead of an orange one?

Why did you install isolated ground receptacles in your home? The only
real application for them is when you have a metallic raceway (conduit)
and want the ground return wire independent of that raceway. I haven't
seen conduit in too many homes yet ;)
