After close of business on Tuesday (February 16) our content management theme — after having provided fairly reliable service for 15 years — will undergo a major upgrade.  This upgrade will enable instant updates across all time zones and across all our social media platforms. We will still be on the job, hosting our Daily Colloquia at the usual hour, our topics will remain as posted on our CALENDAR, but content presentation may look a little janky until the transition stabilizes.

Much like  hardware in ICT, software must also be maintained.

We sweep through the world’s three major time zones; updating our understanding of the literature at the technical foundation of education community safety and sustainability in those time zones 24 times per day. We generally eschew “over-coding” web pages to sustain speed, revision cadence and richness of content as peak priority.  We do not provide a search facility because of copyrights of publishers and time sensitivity of almost everything we do.

Our daily colloquia are typically doing sessions; with non-USA titles receiving priority until 16:00 UTC and all other titles thereafter.  We assume policy objectives are established (Safer-Simpler-Lower-Cost, Longer-Lasting).   Because we necessarily get into the weeds, and because much of the content is time-sensitive and copyright protected, we usually schedule a separate time slot to hammer on technical specifics so that our response to consultations are meaningful and contribute to the goals of the standards developing organization and to the goals of stewards of education community real assets — typically the largest real asset owned by any US state and about 50 percent of its annual budget.

1. Leviathan.  We track noteworthy legislative proposals in the United States 118th Congress.  Not many deal specifically with education community real assets since the relevant legislation is already under administrative control of various Executive Branch Departments such as the Department of Education.

We do not advocate in legislative activity at any level.   We respond to public consultations but there it ends.

We track federal legislative action because it provides a stroboscopic view of the moment — the “national conversation”– in communities that are simultaneously a business and a culture.  Even though more than 90 percent of such proposals are at the mercy of the party leadership the process does enlighten the strengths and weakness of a governance system run entirely through the counties on the periphery of Washington D.C.  It is impossible to solve technical problems in facilities without sensitivity to the zietgeist that has accelerated in education communities everywhere.

Recap of the May meetings of the  Industrial & Commercial Power Systems Conference in Las Vegas.  The conference ended the day before the beginning of the 3-day Memorial Day weekend in the United States so we’re pressed for time; given all that happened.

We can use our last meeting’s agenda to refresh the status of the issues.

IEEE E&H Draft Agenda 28 May 2024

On site conference agenda:

IEEE E&H Conference Agenda 21 May 2024

NESC & NEC Cross-Code Correlation

We typically break down our discussion into the topics listed below:

Codes & Standards:

While IAS/I&CPS has directed votes on the NEC; Mike is the only I&CPS member who is actually submitting proposals and responses to codes and standards developers to the more dominant SDO’s — International Code Council, ASHRAE International, UL, ASTM International, IEC & ISO.  Mike maintains his offer to train the next generation of “code writers and vote getters”

Performance-based building premises feeder design has been proposed for the better part of ten NEC revision cycles.  The objective of these proposals is to reduce material, labor and energy waste owed to the branch and feeder sizing rules that are prescriptive in Articles 210-235.  Our work in service and lighting branch circuit design has been largely successful.  A great deal of building interior power chain involves feeders — the network upstream from branch circuit panels but down stream from building service panel.

Our history of advocating for developing this approach, inspired by the NFPA 101 Guide to Alternative Approaches to Life Safety, and recounted in recent proposals for installing performance-based electrical feeder design into the International Building Code, appears in the link below:

Access to this draft paper for presentation at any conference that will receive it — NFPA, ICC or IEEE (or even ASHRAE) will be available for review at the link below:

Toward Performance-Based Building Premise Feeder Design

 

NFPA 110 Definitions of Public Utility v. Merchant Utility

NFPA 72 “Definition of Dormitory Suite” and related proposals

Buildings:

Renovation economics, Smart contracts in electrical construction.  UMich leadership in aluminum wiring statements in the NEC should be used to reduce wiring costs.

Copper can’t be mined fast enough to electrify the United States

Daleep asked Mike to do a Case Study session on the NEC lighting power density change (NEC 220-14) for the IAS Annual Meeting in October.  Mike agreed.

Exterior Campus & Distribution:

Illumination.  Gary Fox reported that IEEE 3001.9 was endorsed as an ANSI accredited standard for illumination systems.

2024-ICPSD24-0012 PERMANENT DESIGN OF POWER SYSTEMS Parise

This paper details primary considerations in estimating the life cycle of a campus medium voltage distribution grid.   Some colleges and universities are selling their entire power grid to private companies.  Mike has been following these transactions but cannot do it alone.

Variable Architecture Multi-Island Microgrids

District energy:

Generator stator winding failures and implications upon insurance premiums.  David Shipp and Sergio Panetta.  Mike suggests more coverage of retro-fit and lapsed life cycle technicals for insurance companies setting premiums.

Reliability:

Bob Arno’s leadership in updating the Gold Book.

Mike will expand the sample set in Table 10-35, page 293 from the <75 data points in the 1975 survey to >1000 data points.   Bob will set up meeting with Peyton at US Army Corps of Engineers.

Reliability of merchant utility distribution systems remains pretty much a local matter.  The 2023 Edition of the NESC shows modest improvement in the vocabulary of reliability concepts.  For the 2028 Edition Mike submitted several proposals to at least reference IEEE titles in the distribution reliability domain.   It seems odd (at least to Mike) that the NESC committees do not even reference IEEE technical literature such as Bob’s Gold Book which has been active for decades.  Mike will continue to propose changes in other standards catalogs — such as ASTM, ASHRAE and ICC — which may be more responsive to best practice assertions.  Ultimately, improvements will require state public utility commission regulations — and we support increases in tariffs so that utilities can afford these improvements.

Mike needs help from IEEE Piscataway on standard WordPress theme limitations for the data collection platform.

Mike will update the campus power outage database.

Healthcare:

Giuseppe Parise’s recent work in Italian power grid to its hospitals, given its elevated earthquake risk.  Mike’s review of Giuseppe’s paper:

Harvard Business School: Journal of Healthcare Management Standards

Mike and David Shipp will prepare a position paper for the Harvard Healthcare Management Journal on reliability advantages of impedance grounding for the larger systems.

The Internet of Bodies

Forensics:

Giuseppe’s session was noteworthy for illuminating the similarity and differences between the Italian and US legal system in handling electrotechnology issues.

Mike will restock the committee’s library of lawsuits transactions.

Ports:

Giuseppe updates on the energy and security issues of international ports.  Mike limits his time in this committee even though the State of Michigan has the most fresh water international ports in the world.

A PROPOSED GUIDE FOR THE ENERGY PLAN AND ELECTRICAL INFRASTRUCTURE OF A PORT

Other:

Proposals to the 2028 National Electrical Safety Code: Accepted Best Practice, exterior switchgear guarding, scope expansion into ICC and ASHRAE catalog,

Apparently both the Dot Standards and the Color Books will continue parallel development.  Only the Gold Book is being updated; led by Bob Arno.  Mike admitted confusion but reminded everyone that any references to IEEE best practice literature in the NFPA catalog, was installed Mike himself (who would like some backup help)

Universities with Quantum Computing Facilities

Papers in Process:

Impedance Grounding Papers 1 and 2 with David Shipp.  Previous Discussion:

https://ieeetv.ieee.org/channels/ieee-region-events/uc-berkeley-s-medium-voltage-grounding-system

Over Coffee and Beers:

Mike assured Christel Hunter (General Cable) that his proposals for reducing the 180 VA per-outlet requirements, and the performance-base design allowance for building interior feeders do not violate the results of the Neher-McGrath calculation used for conductor sizing.  All insulation and conducting material thermal limits are unaffected.

Other informal discussions centered on the rising cost of copper wiring and the implications for the global electrotechnical transformation involving the build out of quantum computing and autonomous vehicles.  Few expressed optimism that government ambitions for the same could be met in any practical way.

Are students avoiding use of Chat GPT for energy conservation reasons?  Mike will be breaking out this topic for a dedicated standards inquiry session:

NARUC Position on NFPA (NEC) and IEEE (NESC) Harmonization

The standard of care for electrical safety at high and low voltage is set by both the NEC and the NESC. There are gaps, however (or, at best “gray areas”) — the result of two technical cultures: utility power culture and building fire safety culture. There is also tradition. Local system conditions and local adaptation of regulations vary. Where there is a gap; the more rigorous requirement should govern safety of the public and workers.

The 2023 National Electrical Safety Code (NESC)– an IEEE title often mistaken for NFPA’s National Electrical Code (NEC) — was released for public use about six months ago; its normal 5-year revision cycle interrupted by the circumstances of the pandemic.   Compared with the copy cost of the NEC, the NESC is pricey, though appropriate for its target market — the electric utility industry.  Because the 2023 revision has not been effectively “field tested” almost all of the available support literature is, effectively, “sell sheets” for pay-for seminars and written by authors presenting themselves as experts for the battalions of litigators supporting the US utility industry.  Without the ability to sell the NESC to prospective “insiders” the NESC would not likely be commercial prospect for IEEE.   As the lawsuits and violations and conformance interests make their mark in the fullness of time; we shall see the 2023 NESC “at work”.

The IEEE NESC technical committee has released a “fast track” review of proposed changes to fault-managed power system best practice:

CP5605 Provides a definition of new Fault Managed Power System (FMPS) circuits used for the powering of
communications equipment clearly defines what constitutes a FMPS circuit for the purposes of application of the NESC
Rules of 224 and 344
https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXtAAAAADhMnPs

CP5606 Provides new definitions of Communication Lines to help ensure that Fault Managed Power Systems (FMPS)
circuits used for the exclusive powering of communications equipment are clearly identified as communications lines
and makes an explicit connection to Rule 224B where the applicable rules for such powering circuits are found.
https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXpAAAAAFfvWIs

CP5607 The addition of this exception permits cables containing Fault Managed Power System (FMPS) circuits used for
the exclusive powering of communications equipment to be installed without a shield.
https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXuAAAAAEEt3p4

CP5608 The addition of this exception permits cables containing Fault Managed Power System (FMPS) circuits used for
the exclusive powering of communications equipment to be installed without a shield.
https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXvAAAAAGrzyeI

We refer them to the IEEE Education & Healthcare Facilities Committee for further action, if any.

 

August 5, 2022

We collaborate closely with the IEEE Education & Healthcare Facilities Committee (IEEE E&H) to negotiate the standard of care for power security on the #SmartCampus  since many campus power systems are larger than publicly regulated utilities.  Even when they are smaller, the guidance in building the premise wiring system — whether the premise is within a building, outside the building (in which the entire geography of the campus footprint is the premise), is inspired by IEEE Standards Association administrated technical committees.

Northeast Community College | Norfolk, Nebraska

Today we begin a list of noteworthy changes to be understood in the next few Power colloquia.  See our CALENDAR for the next online meeting.

  1. New rules 190 through 195 cover photovoltaic generating stations.  Rule 116c adds an exception for short lengths of insulated power cables and short-circuit protection if the situation involves fewer than 1,000 volts.
  2. Rule 320B has been revised to clarify separations that apply to communications and supply in different conduit systems.
  3. Table 410-4 is based on the latest arc flash testing on live-front transformers.
  4. Rule 092A adds an exception allowing protection, control, and safety battery systems to not be grounded.
  5. Rules 234 B1, C1, D1 were revised to better present vertical and horizontal wind clearances, and to coordinate requirements with the new Table 234-7.
  6. Rule 120A was revised to provide correction factors for clearances on higher elevations.
  7. Table 253-1 has been revised to reduce the load factor for fiber-reinforced polymer components under wire tension—including dead ends—for Grade C construction.
  8. Rule 410A now requires a specific radio-frequency safety program for employees who might be exposed.
  9. In the Clearances section, as well as in the specification of the Grade of Construction in Table 242-1, the Code further clarifies the use of non-hazardous fiber optic cables as telecom providers continue to expand their networks.
  10. Revisions in the Strength & Loading sections include modified Rule 250C, which addresses extreme wind loading for overhead lines. Two wind maps are now provided instead of the previous single one. A map for Grade B, the highest grade of construction, with a Mean Recurrence Interval (MRI) of 100 years (corresponding to a one percent annual probability of occurrence) is provided in place of the previous 50–90-year MRI map. For Grade C construction, a separate 50-year MRI (two percent annual probability of occurrence) map is now provided. In the previous Code, a factor was applied to the 50–90-year MRI map for application to Grade C.
  11. Changes were also made to the method of determining the corresponding wind loads, consistent with the latest engineering practices as an example of a Code revision focused on public safety, the ground end of all anchor guys adjacent to regularly traveled pedestrian thoroughfares, such as sidewalks, and similar places where people can be found must include a substantial and conspicuous marker to help prevent accidents. The previous Code did not require the marking of every such anchor guy.
  12. Significant revisions were made in Section 14 covering batteries. Previous editions of the code were based on lead-acid technology and batteries only used for backup power. The 2023 Code incorporates the new battery technologies and addresses energy storage and backup power.
  13. A new Section 19 of the code covers photovoltaic generating stations, with sections addressing general codes, location, grounding configurations, vegetation management, DC overcurrent protection, and DC conductors. These new rules accommodate large-scale solar power projects.
  14. In the Clearances section, all rules for wireless antenna structures have been consolidated in the equipment section (Rule 238 and 239), which makes the Code more user-friendly.
  15. A new subcommittee was created focusing on generating stations, with the original subcommittee continuing to address substations.
  16. A working group is investigating Fault Managed Power Systems (FMPS) cables as the technology may be used for 5G networks. The team is looking at possible impacts, including clearances and work rules.

Several proposals recommending improvements to the 2017 National Electrical Safety Code (NESC) were submitted to the IEEE subcommittees drafting the 2022 revision of the NESC.   Some of the proposals deal with coordination with the National Electrical Code — which is now in its 2023 revision cycle.  Keep in mind that that NESC is revised every 5 years at the moment; the NEC is revised every 3 years.

The original University of Michigan standards advocacy enterprise has been active in writing the NESC since the 2012 edition and set up a workspace for use by electrical professionals in the education industry.   We will be using this workspace as the 2022 NESC continues along its developmental path:

IEEE 2022 NESC Workspace

The revision schedule — also revised in response to the circumstances of the pandemic — is linked below::

NESC 2023 Edition Revision Schedule*

 

The NESC is a standing item on the 4-times monthly teleconferences of the IEEE Education & Healthcare Facilities committee.  The next online meeting is shown on the top menu of the IEEE E&H website:

IEEE E&H Committee

We have a copy of the first draft of the 2023 NESC and welcome anyone to join us for an online examination during any of Power & ICT teleconferences.  See our CALENDAR for the next online meeting.

Business unit leaders, facility managers and electrical engineers working in the education facilities industry may be interested in the campus power system reliability database.   Forced outages on large research campuses, for example, can have enterprise interruption cost of $100,000 to $1,000,000 per minute.    The campus power system forced outage database discriminates between forced outages attributed to public utility interruptions and forced outages attributed to the university-owned power system.   The E&H committee will convey some of the discipline applied by the IEEE 1366 technical committee into its study of campus power systems and, ultimately, setting a benchmark for the standard of care for large university power systems.

 

 

* The IEEE changed the nominal date of the next edition; likely owed to pandemic-related slowdown typical for most standards developing organizations.
