CEC Ground Electrode Design

[SwiftTarget]

Does anyone have a copy of CEA 249 D 541 reference in Appendix B for rule 36-304(3) in the Canadian Electrical Code? It does not appear that this is available anywhere on the interweb.

From my understanding, it is a white paper "Simplified Rules for Grounding Customer-owned High Voltage Substations", however the CEA (Canadian Electricity Association) website I found elsewhere in this forum is now another organization. I typically reference the requirements in IEEE 80 for ground electrode design but have an inspector requiring I reference the procedure in this standard for compliance. It is especially difficult to do this if I can't get a copy of it.

Thanks in advance.

Without having the paper itself, the reference is described as a research report. This is more like using fundamental methods engineering design than code rules.

CSA paper 1974 Title: Interconnection of Grounds between Stations and Plants may be relevant, attached

Abstract of CEA Report 249 D 542 states: “ ...to determine the
conditions under which the electrical bond between the ground systems of a station and
associated plant may be safely broken. This will enable Electrical Engineers, Inspectors
and Regulatory Authorities to more easily assess the conditions required for separation of
the ground systems.” In the introduction of the same report, it goes on to talk about the
hazardous effects of transferring ground fault potential rise from stations to gas plants
where sparking at insulation breakdown could cause an explosion. It also says that it
would be beneficial to in some instances to separate the plant and station ground systems.
