Power Ohm, USA for Neutral Grounding Resistor
PT. ARLISCO ANUGRAH PRATAMA PRODUCTS
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.
Powerohm Neutral Grounding Resistors feature low coefficient of resistance stainless steel elements. The neutral grounding resistors shall be designed and factory-tested to IEEE Standard 32. In addition, the neutral grounding resistors shall be designed to meet all applicable specifications of ANSI, NEC, NFPA, NEMA, and OSHA. Unless otherwise specified, the neutral grounding resistors shall be designed to conform to Seismic Zone 2 requirements of the Uniform Building Code. A copy of the certified test report will accompany each resistor.
