Resistance-grounded DC systems

[dmcclean]

Is it permissible to install a 100 kVA DC power supply, with split +/- 50 V outputs, where the neutral point of that output is high resistance grounded instead of solidly grounded?

Why or why not?

See 250.162(B).

Am I correct in understanding the Article 100 definitions that, because it doesn't say "solidly" in 250.162(B), that resistance grounding is permissible?

That would not be my opinion.

Interesting, OK, thanks very much. I will do some more reading and try to understand why that is. I appreciate your assistance with finding the right section to look at.
