How to do it
The solidly grounded three-phase generator or transformer-secondary winding is connected in a star or wye arrangement, with the center of the connection designated as the neutral point.
To create a resistance-grounded system, install a voltage-rated resistor that conforms to the IEEE Standard 32 (or C 57.32) between the X0 and ground. It is recommended to monitor this neutral-grounding resistor (NGR) for continuity and alarm (or trip) if it fails.
The NGR limits ground-fault current to a low value that is incapable of sustaining an arc flash. In many cases, the system can continue to operate with one phase faulted to ground, until an orderly shutdown is initiated.
