NEUTRAL GROUNDING RESISTORS LOAD BANKS
INTRODUCTION
RARA Neutral Grounding Resistors are designed to provide added
safety to industrial distribution systems by limiting ground fault
current to reasonable levels. In a typical grounded three phase
system, the NGR is connected directly to the earth ground. This can
cause high ground fault current (typically 10,000 to 20,000 amps)
and excessive damage to transformers, generators, motors, wiring,
and associated equipment. Installing a RARA Neutral Grounding
Resistor between neutral and ground limits fault current to safe
levels while still allowing sufficient current flow to operate fault

Notes
Our NGR elements fall into three categories: Strip, edge wound and wire wound types. The dimensions of these
range from thicknesses of 0.6-2.5mm and widths from 4-100mm. The element type depends on the power of the
NGR. Our enclosuresv have voltage ratings from 0.2KV to 72KV and meet IEEE32. We can manufacturer NGRs
with IP ratings up to IP54 and NEMA ratings up to NEMA3S.
