low resistance gro

Low resistance grounding resistor systems protect power transformers and generators from damaging fault currents. Low resistance grounding of the neutral limits the ground fault current to a high level (typically 50 amps or more) in order to operate protective fault clearing relays and current transformers. These devices are then able to quickly clear the fault, usually within a few seconds. The importance of this fast response time is that it:

  • Limits damage to equipment
  • Prevents additional faults from occurring
  • Provides safety for personnel
  • Localizes the fault
  • UL Listed
  • CSA approved up to 7200v
  • Seismic Zone 4 Certifications and type tests also available
