Scope:  This working group plans to revise the withdrawn IEEE-422 which provides guidance for the design and installation of cable systems in power generating stations.

The organizational meeting of Working Group D14D met on Tuesday, November 6, 2007 during the Fall 2007 ICC meeting at the Doubletree Paradise Valley Resort, Scottsdale, Arizona, with 20 people who signed the attendance sheets.  Chairman, Gary Engmann (Burns & McDonnell; email: gengmann@burnsmcd.com) led the group.  Member Ajit Gwal volunteered to take notes and draft the minutes of the meeting.  Attendees were as follows:

The agenda for the meeting consisted of the following items:

1. Introductions
2. IEEE Copyright, Patents & Inappropriate Topics Policy
3. Roster corrections and prospective volunteers
4. ICC Sub D Presentation
5. Discussion of content – included and not included; overlap with IEEE 666, segregation from IEEE 690
6. Develop proposed Table of Contents
7. Volunteer teams for proposed Clauses
8. Schedule of work
9. Next meeting and location; in conjunction with Power Generation Committee, PES 2008 General Meeting, July 24-28, 2008, in Pittsburg, PA

Chairman Engmann showed slides on IEEE-SA Standards Board bylaws for patent standards and inappropriate topics for IEEE WG meetings.  This meeting focused mainly on the organizational matters and scope.

The following items pertaining to the scope and organization for the revision were discussed:

·Because other IEEE Standards, such as, IEEE-690 addresses Class IE cables for Nuclear Generating Stations, it was suggested not to include nuclear in the new scope of IEEE 422.  Majority of the group accepted this suggestion to exclude the nuclear cables from the scope.

·Inclusion of the upgrades, modification and retrofit work for the generation facilities in the guidance of the new scope of IEEE 422 was discussed.  The group recommended that this guide be used for new station, upgrade and modification and retrofit work.

·It was discussed that the substation cables will not be included the new scope of IEEE 422 because Standard IEEE-525 addresses substation cables.

·New IEEE 422 scope will include a discussion of the 5 kV shielded and non-shielded cables.

·The guide will include the types of cable raceways and conduits used in generation stations.  Member John Merando volunteered to provide a list of the typical raceway and conduit types.  Subsequent to the meeting, the following lists were provided:

oTypes of Raceways: Trays, Ladders, Conduits, Troughs, Gutters, Sleeves, Wireways, Ducts, Ductbanks, Trenches, Direct Burial, Manholes, Handholes, Vaults, Pullboxes, Junction Boxes, Terminal Boxes, False Floors, Plenums

oTypes of Conduit: Electrical metallic tubing (EMT), Electrical non-metallic tubing (ENT), Flexible metal conduit (FMC), Flexible metal tubing (FMT), Rigid galvanized steel (RGS), Intermediate metal conduit (IMC), Liquidtight flexible metal conduit (LFMC), Liquidtight flexible non-metallic conduit (LFNC), Non-metallic underground conduit (NUC), Rigid metallic conduit (RMC), Rigid non-metallic conduit (RNC)

·There was some discussion regarding whether the revised guide should include the application of cables for solar power (600 volts power cables), wind power, ocean waves, and other renewable energy sources, with the consensus of the group indicating that the guide should include these cables applications.

·The new scope will not include safety class 1E cables for nuclear power plants, substation cables, or HVDC /SVC cables, and a discussion of why these cable applications are not included in the IEEE 422 scope will be provided in the introduction section.

·Voltage ratings of the power systems (system voltage and operating voltage) and cable voltage ratings will be included in the scope.  Special cable requirements for the variable frequency drives will also be addressed in the guide.  It was suggested that low voltage power cables are rated “< 1000 volts” and that medium voltage power cables are rated “1 kV -35 kV”.  However, it was noted that the ratings used in this guide should be consistent with ICEA and other IEEE standards.  Further investigation of the system and cable voltage ratings is needed.

·The guide will also include the discussion of cable applications for control, indication, instrumentation, metering, protection, relaying, thermocouple, fiber optics, voice and data communication, and include the new cable types being designed into power stations today.

·Technical topics to be covered will include ampacity, circuit voltage drop, short circuit considerations, installation environment considerations, EMI/RFI effects, electrical segregation, physical separation, rotating equipment failure considerations (i.e. missiles), fire-related issues/concerns and hazardous are classifications.

·The scope will include the engineering design process issues that includes method of analysis, design basis (ambient temperatures etc.), design criteria (such as, expected load current is to be less than cable ampacity), power system analysis (such as, load flow analysis, short circuit analysis and coordination of protective relaying).

·The guide will address issues related to hazardous locations.

·The guide will address special applications or emergency systems, such as, Fire Pumps, and critical circuits such as EBOP (emergency bearing oil pump), and other applications of cables related life safety issues for emergency situations.

·The guide will also address the topics/issues related to Fire Protection and Suppression.  Member Richard Kolich volunteered to provide a draft of the fire protection scope to be included in the guide.  The draft scope will be distributed to the meeting attendees and other WG members for review.  Subsequent to the meeting, the following was provided:

oPassive: Cable Insulation & Jacketing, Fire Stops, Spatial Distances, Coatings, Fire Breaks, Cocoons, Barriers, Blankets, Retardant Sprays

oActive: Portable Extinguishers, Hose Stations, Fixed Extinguishing Systems,

oDetection: Flame, Heat (Fixed and Rate-of-Rise), Smoke (Photoelectric and Combustion Products)

oSuppression: Water, Dry Chemical, Gaseous

The scope will be further discussed in the spring ICC meeting in March 2008 at St Petersburg, Florida, and at the Power Generation Committee meeting in Pittsburgh, PA on July 24-28, 2008.

Minutes were written by Member Ajit Gwal, edited by Vice Chair John Merando and Chairman Gary Engmann and submitted on November 30, 2007.
