How to select the proper neutral-grounding resistor for a high-resistance grounded electrical system
High-resistance grounding (HRG) makes a power distribution system safer and more reliable than the alternatives. High-rresistance grounding can limit point-of-fault damage, eliminate transient ...
It has been proposed to add some fairly small and inexpensive resistors in the transformers’ ground connections. The addition of that little bit of resistance would significantly reduce the amount of ...
