Not sure if they were the same standards, but we basically had to run a
separate transformer just for the computer equipment.  Same rule applied,
though, "safety" ground was tied to neutral at only one place (transformer
secondary).  The outlets were "isolated ground", meaning the third wire was
NOT tied to the conduit or box at the outlet.

After some bad experiences, all of our field installations included
isolation transformers as well.  On one trip (to 'Red' China), I left with
16 spare power supplies and came back with 17 failed power supplies.
