Common problems in commissioning of HRG systems

Abstract

This document discusses some common mistakes that are made in the commissioning of High Resistance Grounding (HRG) systems. While high resistance grounding has been in use for some time, many commissioning teams are less familiar with HRG systems and various issues can arise in the commissioning process. Topics discussed include: compatibility of equipment with HRG systems; how system configuration affects testing and verification; and key points for training programs.
