Neutral grounding resistor assemblies
Scope:
Note: The title & scope for this NOI (originally published on June 11, 2024) was updated by the responsible SDO on February 18, 2025.
1.1
This Standard applies to neutral grounding resistor assemblies that are used to limit the ground fault current or the voltage to ground of an electrical power system, when installed in accordance with the Canadian Electrical Code, Part I.
1.2
This Standard applies to neutral grounding resistor assemblies for use in electrical power systems rated 72 kV line to line less.
1.3
Neutral grounding resistor assemblies may be of an open type for mounting in other equipment.
1.4
Neutral grounding assemblies may contain components and circuits for sensing and signalling.
1.5
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
Project need:
To update the current standard due to user experience / feedback / new technology by creating a new edition of this standard. This proposed New Edition is being developed at the request of Industry, Regulators, and Certificationagencies. It will provide the industry with updated references and requirements based on current best practices.
