Most electricians understand that bonding and grounding is a priority when it comes to the safety of building wiring systems. They’re taught early on in their ...
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 ...
When designing ground-fault protection (GFP) for a power distribution system, you should always consider the nature of the power source. If the power source is from a separately derived system, you ...
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 ...
Neither a high resistance-grounded system nor an underground system can supply line-to-ground loads. If protection and monitoring equipment is connected from line to ground, then it must not threaten ...
