November 2001 meeting of SC-05-05

[Last printing 2 January 2002] Report of the SC-05-05 Working Group on Grounding and EMC Practices of the SC-05 Subcommittee on Interconnections meeting, held in conjunction with the AES 111th Convention in New York, New York, US, 2001-11-29

Chair B. Olson convened the meeting. The agenda and the report from the previous meeting were approved as written.

Current development projects

AES-X13 Guidelines for Grounding

The current PWD (X13AES30PWD-010911JB.DOC) that is on the FTP site was discussed. Another lively discussion was had regarding various definitions and their ability to be understood clearly by all readers. Most were resolved, and the few that remain will be brought for discussion on the reflector.

Discussion regarding the grounding of splitter boxes helped to clarify the wording.

In the PWD, 4.6.3 will have a note added that will more clearly indicate that this is an alternative, although less desirable than the previous clauses. and will be switched so that the most desirable alternative is indicated first.

The information in 4.8 regarding cable imbalances will be investigated by D. DeSmidt using Belden data and he will suggest achievable real world numbers.

After the above items have been discussed on the reflector, a new PWD will be posted. The goal is to have a PCFC ready by 2002-03.
