Hi,
I have five 13.8 KV generators each rated 1.7 MW each. It is an emegency gen system for a mining application.
Here is my question: I have experience with 600 V emergency generator systems. Here is my policy for grounding:
"In case of emegency generator installation, If emergency generator has to operate in parallel with utility, then It needs to have a seprate ground and should be also connected to utility ground other wise it does not need to have a seprate ground. I am talking about 600 V level. "
Do I need to have a seprate Low resistance grounding for these 13.8 KV generators and also connect them to utility ground.
Actually the dilemna is that: How do I decide that this generator needs to have its own grounding or only utility ground will be fine.
I apologize, if I was not able to express my self clearly.
Thanks
