Type NR Neutral Grounding Resistors

by Powerohm 

Powerohm Type NR Neutral Grounding Resistors are used in industrial power systems for resistance grounding of wye connected generators and transformers. A neutral grounding resistor limits the fault current to a value which is sufficient enough to operate protective relays, yet prevent unwanted fault damage.

  • Reduced overvoltages.
  • Reduced equipment damage.
  • Isolation of faulted circuit.
  • Increased protection of transformers, generators and auxiliary equipment.
  • Reduced operation/maintenance expense.
  • Increase safety.
  • Improved reliability.
  • Reduced frequency of faults.
  • Quicker fault location.
  • Increased lightning protection.
Low coefficient of resistance and are designed to meet all applicable specifications of ANSI, NEC, NFPA, NEMA, and OSHA
