Grounding System Testing

The Fall-of-Potential (FOP) method is plagued by inherent pitfalls, such as de-energization, long lead lengths, interference, and lack of confidence in data. IEEE Standard 81 prescribes the Computer Based Test (CBT) method which overcomes these issues by:

  • Enabling testing at energized sites
  • Significantly reducing test lead lengths
  • Filtering out EMI, RFI, and ground current noise
  • Providing probe performance, data quality, and error identification

HP&D grounding specialists interpret CBT data that facility owners use to make informed decisions. HP&D offers a wide range of  testing, including:

HP&D grounding specialists use the Smart Ground® Multimeter (SGM)*, which, unlike other devices, doesn’t require de-energization or isolation. It can validate the safety of a ground grid designed by any software such as CDEGS, WinIGS, CYMGRD, ETAP, EDSA, SKM, etc.

* HP&D is the exclusive worldwide distributor of the Smart Ground® Multimeter (SGM), a multi-function device for measuring grounding systems.
