grounding
(OP)
Hello All,
We have a new system that is fed from a single D-Y transformer. We are now adding an alternate source (a generator). We would like to resitance ground both sources.
The questions is can this be done with one NGR? The suggestion was made to place a zigzag with NGR in the secondary lineup so that we only need one NGR for both sources....does a zigzag work fine on a the secondary of a wye transformer?

The zig-zag is the joker. It is used one of several methods used to generate or develop a neutral point for grounding when one does not exist. Artificial neutrals are superfluous when a true neutral such as a wye point exists.
This brings us back to Rafiq's suggestion, hire someone who knows grounding.
As for a single NGR, not enough information to say. It depends.

What is the KVA rating of the generator?
Is the generator wye or delta?
