October 2002 meeting of SC-05-05
Report of SC-05-05 Working Group on Grounding and EMC Practices of the SC-05 Subcommittee on Interconnections meeting, held in conjunction with the AES 113th Convention in Los Angeles, CA, US, 2002-10-04
Chair B. Olson convened the meeting.
The agenda and the report of the meeting held in conjunction with the AES 112th Convention in Munich, 2002-05, was accepted as written.
Open projectsAES-X13 Guidelines for Grounding
The current PCFC has become unmanageably large and convoluted. The chair has proposed that instead there should be multiple documents that deal with individual issues raised in the current document.
The chair recommends that the current PCFC be withdrawn, and a new PWD was proposed to more adequately describe the original intent of the PIR. This draft was discussed and will be posted to the WG site. B. Whitlock presented appropriate drawings to be included and will forward them to the WG site.
R. Rayburn suggested a renaming of the project to Guidelines for Shielding.
The meeting felt that the Appendix of the AES-X13 draft should be rewritten as an Engineering Report. Proposals for additional reports or standards based on other portions of the draft are requested by the chair.
AES-X27 Test Methods for Measuring Electromagnetic Interference
This document will be written as an Engineering Report outlining useful procedures for measuring the electromagnetic interference created by real-world conditions.
One intent is to encourage the manufacture of a low-cost test generator that will allow suitable testing of equipment using a variety of test fixtures.
Another intent is to describe procedures that can be used with radios or cellular telephones as the interference source. These radios and cellular telephones would need to be used in their normal operation by licensed operators, if required by local statutes.
AES-X35 Installation Wiring Practices
Some testing on cable types is ongoing by certain members of the committee that will be helpful in determining useful guidelines.
R. Chinn agreed to be be the editor for this document, accepting various source material from authors and putting them into a common writing style. Suggestions should be sent to the WG chair.
AES-X112 XLR Free Connectors with Nonconducting Shells
It was proposed to create an Information Document on applications of connectors for facilities. It was felt necessary to explain stopgap measures that use nonconductive covers to prevent inadvertent ground connections to the shielding contact.
This work should ultimately appear as part of the X35 document.
AES-X125 Input Filtering for Electromagnetic Compatibility
No progress was reported.
New projectsThere were no new projects.
New businessThere was no new business.
The next meeting is scheduled to be held in conjunction with the AES 114th Convention in Amsterdam, The Netherlands.
