Most PV solar sites I have provided the relay settings range from 20-300 MW with a collector substation feeding multiple 12-34 kV circuits. At the substation there is typically a wye-delta-wye transformer without a neutral ground resistor. Discussing coordination with another engineer at a...
I've done some casual research, such as looking into OSHA, and I have not been able to understand how often touch or step voltages occur. I'm generally looking at substations where IEEE Std 80 applies, and I find only a couple instances that are clear touch voltage injuries. Looking outside the...
