Performance Test Your Facility’s Grounding System

Is the grounding system of your facility working as it should? Over time changes in soil resistivity, grounding rods, and bonded connections can degrade. An inadequate grounding system may:

  • Create unintended paths that could result in a shock hazard to employees
  • Increase equipment failure rates
  • Cause instrumentation errors
  • Result in power factor problems
  • Cause many other intermittent power problems

The NEC establishes the standard of the impedance to ground value of 25 ohms or less as being an acceptable test result. Many facilities with sensitive electronic equipment use a standard of 5 ohms or less. An assessment every 2 years is recommend, it is important to build a baseline and then track future readings to determine the performance metrics of your ground system.

A key point of emphasis of NFPA 70E is “safety-related maintenance”.  NFPA 70E states that electrical equipment shall be maintained to reduce the risk of failure and the subsequent exposure to electrical hazards.  So what might be included in your electrical maintenance program?

ASG’s Switchgear Fit and Health Program is designed to meet the standards described to NFPA 70E. Our TEGG Services – energized testing protocol is completed for the top tier components of your electrical system. The testing services include an infrared, ultrasonic and visual inspection protocol.

Based upon the data gathered, and problems identified, a detailed de-energized maintenance plan is developed for each as inventoried during the energized testing session. The de-energized task plan is completed along with any repairs as identified during the energized session. Looking for more details? See:  Switchgear Fit and Healthy

Reliability, safety, protection, and preservation of your sites electrical assets are the results achieved with the scope of work provided in ASG’s Switchgear Fit and Health services.
