Medium-voltage motors are critical to a facility’s power system. Not only are they expensive, but their failure can have crippling, long-lasting impacts on a plant’s operation. As such, properly ...
One of the most important aspects of a safe electrical power system is the proper performance of ground-fault protective equipment. Mandated by the National Electrical Code (NEC), Art. 230.95(C) ...
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 ...
