Farm Electrical Power

Sunday, Animal, Farm, Agri

Many land grant colleges and universities are stewards of agricultural facilities that require reliable electrical power that is safe and sustainable for livestock and animal habitat for sporting.

FREE ACCESS: 2023 National Electrical Code

The premise wiring rules for hazardous university owned buildings have been relatively stable.  Electrical professionals are guided by:

  1. Farm Load Calculations of Part V of Article 220,
  2. Corrosion mitigation with appropriate specification of power chain wiring
  3. Stray voltage and the equipotential plane
  4. Interactivity with regulated utility power sources.

Public response to the First Draft of the 2026 National Electrical Code will be received until August 28, 2024.  We coordinate our approach to the entire NFPA electrical suite with the IEEE Education & Healthcare Facilities Committee which meets 4 times monthly.  We typically refer to previous transcripts of technical committee actions to inform any changes (improvements) that we propose, if any:

Readings / The Administrative State

In power system engineering, availability and reliability are two important concepts, but they refer to different aspects of the system’s performance.

Reliability:

  • Reliability refers to the ability of a power system to perform its intended function without failure for a specified period under given operating conditions. It is essentially a measure of how dependable the system is.
  • Reliability metrics often include indices such as the frequency and duration of outages, failure rates, mean time between failures (MTBF), and similar measures.
  • Reliability analysis focuses on identifying potential failure modes, predicting failure probabilities, and implementing measures to mitigate risks and improve system resilience.Availability:
  • Availability, on the other hand, refers to the proportion of time that a power system is operational and able to deliver power when needed, considering both scheduled and unscheduled downtime.
  • Availability is influenced by factors such as maintenance schedules, repair times, and system design redundancies.
  • Availability is typically expressed as a percentage and can be calculated using the ratio of the uptime to the total time (uptime plus downtime).
  • Availability analysis aims to maximize the operational readiness of the system by minimizing downtime and optimizing maintenance strategies.

Reliability focuses on the likelihood of failure and the ability of the system to sustain operations over time, while availability concerns the actual uptime and downtime of the system, reflecting its readiness to deliver power when required. Both concepts are crucial for assessing and improving the performance of power systems, but they address different aspects of system behavior.

 UPDATED POLICIES ON U.S. DECARBONIZATION AND TECHNOLOGY TRANSITIONS

June 15:FERC Finalizes Plans to Boost Grid Reliability in Extreme Weather Conditions

On Monday June 13th, Federal Energy Regulatory Commission commissioners informed the House Committee on Energy and Commerce that the “environmental justice” agenda prohibits reliable dispatchable electric power needed for national power security. One megawatt of natural gas generation does not equal one megawatt of renewable generation. The minority party on the committee — the oldest standing legislative committee in the House of Representatives (established 1795) — appears indifferent to the reliability consequences of its policy.

Joint Federal-State Task Force on Electric Transmission

“Our nation’s continued energy transition requires the efficient development of new transmission infrastructure. Federal and state regulators must address numerous transmission-related issues, including how to plan and pay for new transmission infrastructure and how to navigate shared federal-state regulatory authority and processes. As a result, the time is ripe for greater federal-state coordination and cooperation.”

Evensong “Melody in F”

Evensong services are typically held in cathedrals, collegiate chapels, and large parish churches, where choral music plays a prominent role. These services often feature the singing of psalms, choral anthems, hymns, and other sacred music.  The Evensong tradition holds a significant place in Western civilization due to its historical and cultural importance. It has provided a space for prayer, reflection, and worship for centuries, connecting individuals with their faith and providing a sense of spiritual solace.

The beauty and solemnity of the music performed during Evensong services have also contributed to the development of Western sacred music, with composers creating choral works specifically for these occasions.

Biodiversity

“Biodiversity Illustration for Soñaderno” Maria Paula Sanabria López
•

As described in April, a  new ISO Technical Committee, ISO/TC 331 – Biodiversity, has been formed. The Secretariat has been assigned to France (AFNOR).  ISO/TC 331 will operate under the following scope:

Included: Standardization in the field of Biodiversity to develop requirements, principles, framework, guidance and supporting tools in a holistic and global approach for all relevant organizations, to enhance their contribution to Sustainable Development.

Excluded: standardization of test and measurement methods for ecological quality of water, air, soil and marine environment.

Organizations interested in serving as the U.S. TAG Administrator or participating on the U.S. TAG should contact ANSI’s ISO Team (isot@ansi.org).  Public consultation closes 6 January 2021

All ISO best practice titles relevant to US education communities remain on the standing agenda of our Global colloquia.  See our CALENDAR for the next online meeting; open to everyone.

Posted 1 April 2020 

 

The Association Française de Normalisation (AFNOR), the International Organization for Standardization (ISO) member body for France has submitted a proposal for a new field of ISO technical activity on Biodiversity, with the following scope statement:

Standardization in the field of Biodiversity to develop requirements, principles, framework, guidance and supporting tools in a holistic and global approach for all relevant organizations, to enhance their contribution to Sustainable Development.  Excluded: standardization of test and measurement methods for ecological quality of water, air, soil and marine environment.

It is intended to support organizations of any type or activities in addressing biodiversity over the whole value chain: upstream, on site, and downstream. It will help in developing action plans and to monitor their progress with new or existing tools such as indicators, inventory methods, standards for environmental bio-monitoring or biodiversity reporting.

Anyone wishing to review the proposal can request a copy by contacting ANSI’s ISO Team (isot@ansi.org), with a submission of comments to Steve Cornish (scornish@ansi.org) by close of business on Friday, April 17, 2020.   We know Steve well enough to know that on a project like this, he would welcome comment first thing Monday morning; owing to the disruption of the normal course of business over the past ffew weeks.

If the ISO receives acceptance by global stakeholders, this would be an ideal project for a US-based academic unit to sponsor as one of ANSI’s Technical Advisory Groups.

We maintain all ISO consensus products on the standing agenda of our International Standards teleconferences.  We have the project prospectus now .  See our CALENDAR for the next online meeting; open to everyone.

Inside Gasson Tower

Boston College is a private Jesuit research university in Chestnut Hill, Massachusetts.  Gasson Hall is a symbol of Boston College, representing the university’s commitment to academic excellence, spiritual values, and the pursuit of knowledge.  It The hall continues to serve as an important part of the Boston College campus, housing administrative offices, classrooms, and the university’s Honors Program.

In “The Social Network,” Gasson Hall was used as a filming location for several scenes that take place at Harvard University, which is where Mark Zuckerberg attended college before he created Facebook. Specifically, Gasson Hall was used as a stand-in for Harvard’s Memorial Hall, which is a large Gothic Revival building that houses a dining hall and a chapel.

The scene in “The Social Network” that was filmed in Gasson Hall shows Mark Zuckerberg (played by Jesse Eisenberg) and Eduardo Saverin (played by Andrew Garfield) attending a disciplinary hearing in front of the Harvard administration. The hearing takes place in a large ornate room with stained glass windows and a high vaulted ceiling, which is actually the Reading Room on the third floor of Gasson Hall. The filmmakers made some minor changes to the room, such as adding a portrait of John Harvard and replacing some of the furniture, but overall, the space is very recognizable as Gasson Hall.
