Campus Outdoor Lighting

“The Starry Night” | Vincent van Gogh

The IEEE Education & Healthcare Facilities Committee has completed a chapter on recommended practice for designing, building, operating and maintaining campus exterior lighting systems in the forthcoming IEEE 3001.9 Recommended Practice for the Design of Power Systems for Supplying Commercial and Industrial Lighting Systems; a new IEEE Standards Association title inspired by, and derived from, the legacy “IEEE Red Book“.  The entire IEEE Color Book suite is in the process of being replaced by the IEEE 3000 Standards Collection™  which offers faster-moving and more scaleable, guidance to campus power system designers.

Campus exterior lighting systems generally run in the 100 to 10,000 fixture range and are, arguably, the most visible characteristic of public safety infrastructure.   Some major research universities have exterior lighting systems that are larger and more complex than cooperative and municipal power company lighting systems which are regulated by public service commissions.

While there has been considerable expertise in developing illumination concepts by the National Electrical Manufacturers Association, Illumination Engineering Society, the American Society of Heating and Refrigeration Engineers, the International Electrotechnical Commission and the International Commission on Illumination, none of them contribute to leading practice discovery for the actual power chain for these large scale systems on a college campus.   The standard of care has been borrowed, somewhat anecdotally, from public utility community lighting system practice.  These concepts need to be revisited as the emergent #SmartCampus takes shape.

Electrical power professionals who service the education and university-affiliated healthcare facility industry should communicate directly with Mike Anthony (maanthon@umich.edu) or Jim Harvey (jharvey@umich.edu).  This project is also on the standing agenda of the IEEE E&H committee which meets online 4 times monthly — every other Tuesday — in European and American time zones.  Login credentials are available on its draft agenda page.

2025 Third Quarter Report

Here we shift our perspective 120 degrees to understand the point of view of the Producer interest in the American national standards system (See ANSI Essential Requirements).  The title of this post draws from the location of US and European headquarters.  We list proposals by a successful electrical manufacturer for discussion during today’s colloquium:

2026 National Electrical Code

CMP-1: short circuit current ratings, connections with copper cladded aluminum conductors, maintenance to be provided by OEM, field markings

CMP-2: reconditioned equipment, receptacles in accessory buildings, GFCI & AFCI protection, outlet placement generally, outlets for outdoor HVAC equipment(1)

(1) Here we would argue that if a pad mount HVAC unit needs service with tools that need AC power once every 5-10 years then the dedicated branch circuit is not needed.  Many campuses have on-site, full-time staff that can service outdoor pad mounted HVAC equipment without needing a nearby outlet.  One crew — two electricians — will run about $2500 per day to do anything on campus.

CMP-3: No proposals

CMP-4: solar voltaic systems (1)

(1) Seems reasonable – spillover outdoor night time lighting effect upon solar panel charging should be identified.

CMP-5: Administrative changes only

CMP-6: No proposals

CMP-7: Distinction between “repair” and “servicing”

CMP-8: Reconditioned equipment

CMP-9: Reconditioned equipment

CMP-10: Short circuit ratings, service disconnect, disconnect for meters, transformer secondary conductor, secondary conductor taps, surge protective devices, disconnecting means generally, spliced and tap conductors, more metering safety, 1200 ampere threshold for arc reduction technology, reconditioned surge equipment shall not be permitted, switchboard short circuit ratings

Transmission Line Right-of-Way

 

Optimization of Transmission Line Right-of-Way

Ajaykumar Patel, et. al

School of Engineering & Technology, Central Queensland University, Melbourne, Australia

 

Abstract: A specific land is required to design the transmission line to construct effectively and maintain properly is called right of way of transmission line. It is calculated by considering mainly three electrical quantity related transmission line such as electric field, magnetic field and radio interference. Corona effect is considered for the evolution of right of way. By considering these parameters, it provide idea related to effect surrounding the area nearby transmission line.

The determination of transmission line right of way for public electric utilities typically involves a combination of legal considerations, regulatory requirements, environmental assessments, and public engagement: 

Planning and Route Selection: Public electric utilities assess their power transmission needs based on factors such as population growth, energy demand, and infrastructure upgrades. They consider various potential routes and alternatives, taking into account factors like terrain, existing infrastructure, land use, and environmental sensitivities.

Environmental and Impact Assessments: Utilities conduct environmental and impact assessments to evaluate the potential effects of the proposed transmission line routes. These assessments examine factors such as wildlife habitats, endangered species, wetlands, water bodies, cultural or historical sites, and scenic landscapes. The purpose is to identify potential impacts and propose mitigation measures.

Regulatory and Permitting Process: Public utilities must comply with applicable laws and regulations governing transmission line development. This includes obtaining necessary permits and approvals from relevant regulatory agencies at the federal, state, and local levels. The requirements vary depending on the jurisdiction, but they often involve environmental agencies, land management agencies, and public utility commissions.

Public Engagement and Consultation: Utilities engage in public consultation and outreach to gather feedback from affected communities, landowners, and stakeholders. They conduct public hearings, open houses, and meetings to inform the public about the project, address concerns, and consider alternative routes suggested by the community. This engagement helps ensure transparency and public input in the decision-making process.

Negotiations and Eminent Domain: Utilities negotiate with landowners along the proposed transmission line route to acquire the necessary right of way. In some cases, if an agreement cannot be reached, utilities may exercise eminent domain, which is a legal process that allows them to acquire the land for public use while providing just compensation to the affected landowner.

Legal Framework: The legal framework for determining transmission line right of way varies by jurisdiction. Laws related to land use, zoning, environmental protection, and eminent domain play a role in defining the process and requirements for securing right of way.

Procedures vary depending on the country, state, or region where the transmission line is being developed. Local regulations, environmental conditions, and public engagement practices will influence the overall process.

“Landscape between Storms” 1841 Auguste Renoir

 

When is it ever NOT storm season somewhere in the United States; with several hundred schools, colleges and universities in the path of them? Hurricanes also spawn tornadoes. This title sets the standard of care for safety, resilience and recovery when education community structures are used for shelter and recovery.  The most recently published edition of the joint work results of the International Code Council and the ASCE Structural Engineering Institute SEI-7 is linked below:

2020 ICC/NSSA 500 Standard for the Design and Construction of Storm Shelters.

Given the historic tornados in the American Midwest this weekend, its relevance is plain.  From the project prospectus:

The objective of this Standard is to provide technical design and performance criteria that will facilitate and promote the design, construction, and installation of safe, reliable, and economical storm shelters to protect the public. It is intended that this Standard be used by design professionals; storm shelter designers, manufacturers, and constructors; building officials; and emergency management personnel and government officials to ensure that storm shelters provide a consistently high level of protection to the sheltered public.

This project runs roughly in tandem with the ASCE Structural Engineering Institute SEI-17 which has recently updated its content management system and presented challenges to anyone who attempts to find the content where it used to be before the website overhaul.    In the intervening time, we direct stakeholders to the link to actual text (above) and remind education facility managers and their architectural/engineering consultants that the ICC Code Development process is open to everyone.

1264-2022 – IEEE Guide for Animal Mitigation for Electric Power Supply Substations

IEEE Power Engineering Society

Abstract: Documented in this guide are methods and designs to mitigate interruptions, equipment damage, and personnel safety issues resulting from animal intrusions into electric power supply substations, thereby improving reliability and safety, and minimizing the associated revenue loss.
Scope: This guide documents methods and designs to mitigate interruptions, equipment damage, and personnel safety issues resulting from animal intrusions into electric power supply substations, thereby improving reliability and safety, and minimizing the associated revenue loss.
Purpose: Intrusion by animals into electric power supply substations has been a problem experienced by most of the electric utility industry. The costs associated with outages caused by animals continue to escalate. Although animal problems differ in nature geographically, the damage to equipment, interruption of or loss of service to customers, and safety problems encountered by operating personnel result in similar general concerns. This guide identifies various animals, the problems they cause, and mitigation methods. Further, it recommends criteria for applying mitigation methods, documents survey-reported effectiveness of various methods, and recommends factors for evaluating effectiveness of methods once they are applied.

Wires

Ampere current flows through copper or aluminum conductor due to the movement of free electrons in response to an applied electric field of varying voltages.   Each copper or aluminum contributes one free electron to the electron sea, creating a vast reservoir of mobile charge carriers. When a potential difference (voltage) is applied across the ends of the conductor, an electric field is established within the conductor. This field exerts a force on the free electrons, causing them to move in the direction of the electric field.  The resulting current flow can be transformed into different forms depending on the nature of the device.

Heating: When current flows through a resistor, it encounters resistance, which causes the resistor to heat up. This is the principle behind electric heaters, toasters, and incandescent light bulbs.

Mechanical Work: Current flowing through an electric motor creates a magnetic field, which interacts with the magnetic field of the motor’s permanent magnets or electromagnets. This interaction generates a mechanical force, causing the motor to rotate. Thus, electrical energy is converted into mechanical energy; including sound.

Light: In an incandescent light bulb, a filament heats up ( a quantum phenomena) due to the current passing through it. This is an example of electrical energy being converted into light energy; including the chemical energy through light emitting diodes

Today we dwell on how conductors are specified and installed in building premise wiring systems primarily; with some attention to paths designed to carry current flowing through unwanted paths (ground faults, phase imbalance, etc).   In the time we have we will review the present state of the best practice literature developed by the organizations listed below:

Institute of Electrical and Electronic Engineers

National Electrical Safety Code

Insulated Cable Engineers Association

International Association of Electrical Inspectors

National Fire Protection Association

Children’s Hospital Neonatal Intensive Care

Some of the common electro-technologies used in a neonatal care unit include:

  • Incubators: These temperature-controlled units create a controlled environment to keep premature or sick infants warm and protected.
  • Ventilators: Mechanical ventilators assist newborns with respiratory distress by delivering oxygen and helping them breathe.
  • Monitors: These devices track vital signs such as heart rate, oxygen levels, blood pressure, and temperature to ensure the baby’s health and detect any abnormalities.
  • Phototherapy Lights: Special lights are used to treat jaundice in newborns, helping to break down excess bilirubin in the blood.
  • Intravenous Pumps: These pumps are used to deliver medications, fluids, and nutrients directly into the baby’s bloodstream.
  • Feeding Tubes: For infants who are unable to feed orally, feeding tubes are used to deliver breast milk or formula directly into their stomach.
  • Blood Gas Analyzers: These machines measure the levels of oxygen, carbon dioxide, and other gases in a baby’s blood to monitor respiratory status and acid-base balance.
  • Infusion Pumps: Used to administer controlled amounts of fluids, medications, or nutrients to newborns.
  • CPAP/BiPAP Machines: Continuous Positive Airway Pressure (CPAP) and Bi-level Positive Airway Pressure (BiPAP) machines help newborns with breathing difficulties by providing a continuous flow of air pressure.
  • Neonatal Resuscitation Equipment: This includes equipment such as resuscitation bags, endotracheal tubes, laryngoscopes, and suction devices used during emergency situations to assist with newborn resuscitation.

It’s important to note that specific tools and equipment may vary depending on the level of neonatal care provided by the unit, the needs of the infants, and the policies of the healthcare facility.

Neonatal care, as a specialized field, has been shaped by the contributions of several pioneers in medicine. Here are a few notable figures who have made significant advancements in neonatal care:

  • Dr. Virginia Apgar was an American obstetrical anesthesiologist who developed the Apgar score in 1952. The Apgar score is a quick assessment tool used to evaluate the overall health of newborns immediately after birth. It assesses the baby’s heart rate, respiratory effort, muscle tone, reflex irritability, and color, providing valuable information for prompt intervention and monitoring.
  • Dr. Martin Couney, a pioneering physician, established incubator exhibits at world fairs and amusement parks in the early 20th century. He promoted the use of incubators to care for premature infants and played a significant role in popularizing the concept of neonatal intensive care.
  • Dr. Virginia A. Apgar, an American pediatrician and neonatologist, made significant contributions to the field of neonatology. She specialized in the care of premature infants and conducted extensive research on neonatal resuscitation and newborn health. She also developed the Apgar scoring system, although unrelated to Dr. Virginia Apgar mentioned earlier.
  • Dr. Lula O. Lubchenco was an influential researcher and neonatologist who made important contributions to the understanding of newborn growth and development. She developed the Lubchenco Growth Chart, which provides a standardized assessment of a newborn’s size and gestational age, aiding in the identification and monitoring of growth abnormalities.
  • Dr. Mary Ellen Avery was a renowned American pediatrician and researcher whose work focused on understanding and treating respiratory distress syndrome (RDS) in premature infants. She identified the importance of surfactant deficiency in RDS and contributed to the development of surfactant replacement therapy, revolutionizing the care of preterm infants.

These individuals, among many others, have played pivotal roles in advancing the field of neonatal care, improving the understanding, diagnosis, treatment, and overall outcomes for newborn infants.
