About

CEC Section 10-302 specifies that all neutral grounding resistors (NGRs) must be monitored for both open and shorted conditions in addition to detecting ground faults downstream of the source. The key challenge when monitoring an NGR for these conditions is when you have more than one NGR in the system. This instance frequently occurs when generators are operating in parallel to provide emergency/backup power for buildings. In this lounge and learn, Bender examines different monitoring configurations for the NGRs in paralleling generator applications that can meet code requirements through active measurement principles and switching devices.


Key Topics Covered

  • Understand the applicable code requirements for NGR monitoring based on CEC Section 10-302
  • Theory of operation of HRG systems
  • Examine how active and passive measurement principles monitor the integrity of paralleling NGRs
