FYI. I was able to locate a useful tool. An older white paper that I am not sure is available via the web. Anyway, I thought I would note the source in case others find it useful.
Westinghouse Industrial and Commercial Power System Application Series White Paper (PRSC-4A dated January 1978)...
Thanks Rockman. Agreed. The issue is that the distribution system does not yet exist so measurement is not possible. The neutral resistance of the generator plant needs to be specified equal or higher than the anticipated charging current.
I understand charging current is proportional to the distance between conductors thus the response about the significance of overhead vs underground. In this case all phase conductors are in conduits so I don't suspect it matters whether or not the conduits are underground.
The only...
I have a project that is in design phase that includes paralleled 12.47kV diesel generators feeding a medium voltage distribution system. I am planning to specify a high resistance ground (HRG) for the generators. I understand that the let through current of the HRG must be equal to or greater...
