Stray Voltage: Sources and Solutions

Truman C. Surbrook – Norman D. Reese – Angela M. Kehrle

 

Abstract.  Stray voltage is caused by voltage drop and ground faults and may have its origin on the primary electrical distribution system or on the customer’s secondary electrical system. The rms value of the neutral-to-earth voltage along a primary distribution line may be at a value of zero some distance from the substation depending on the condition of the conductor resistances, grounding resistances, and the amount of load. Neutral-to-earth resistance is not the cause of stray voltage; however, the value of this resistance to earth at a particular location will affect the level of stray voltage. A four-wire single-phase feeder system supplying farm buildings from a single metering point is effective in preventing on-farm secondary neutral voltage drop, provided the four-wire system is extended to all farm loads, and provided no high-magnitude ground faults are present. Isolation of the primary and secondary neutral systems at the distribution transformer is effective in preventing off-farm sources from entering the customer’s system. This separation may be accomplished using a number of commercially available devices.

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.

We revisit first principles regarding the a safety “buffer zone” enforced by code to make high-voltage infrastructure compatible with surrounding development. Ignoring it risks lives, property, and legal issues—hence the detailed regulatory focus on design (calculations), construction (compliance checks), and management (lifetime enforcement), especially critical around expansive campus boundaries. Often these zones define where new facilities can be built.

The purpose of the code is to establish minimum requirements to provide a reasonable level of health, safety, property protection and welfare by controlling the design, location, use or occupancy of all buildings and structures through the regulated and orderly development of land and land uses within this jurisdiction.

Municipalities usually have specific land use or zoning considerations to accommodate the unique needs and characteristics of college towns:

  1. Mixed-Use Zoning: Cities with colleges and universities often employ mixed-use zoning strategies to encourage a vibrant and diverse urban environment. This zoning approach allows for a combination of residential, commercial, and institutional uses within the same area, fostering a sense of community and facilitating interactions between students, faculty, and residents.
  2. Height and Density Restrictions: Due to the presence of educational institutions, cities may have specific regulations on building height and density to ensure compatibility with the surrounding neighborhoods and maintain the character of the area. These restrictions help balance the need for development with the preservation of the existing urban fabric.
  3. Student Housing: Cities with colleges and universities may have regulations or guidelines for student housing to ensure an adequate supply of affordable and safe accommodations for students. This can
    include requirements for minimum bedroom sizes, occupancy limits, and proximity to campus.
  4. Parking and Transportation: Given the concentration of students, faculty, and staff, parking and transportation considerations are crucial. Cities may require educational institutions to provide parking facilities or implement transportation demand management strategies, such as promoting public transit use, cycling infrastructure, and pedestrian-friendly designs.
  5. Community Engagement: Some cities encourage colleges and universities to engage with the local community through formalized agreements or community benefit plans. These may include commitments to support local businesses, contribute to neighborhood improvement projects, or provide educational and cultural resources to residents.

  1. Reed v. Town of Gilbert (2015): This Supreme Court case involved a challenge to the town of Gilbert, Arizona’s sign code, which regulated the size, location, and duration of signs based on their content. The court held that the sign code was a content-based restriction on speech and therefore subject to strict scrutiny.
  2. City of Ladue v. Gilleo (1994): In this Supreme Court case, the court struck down a municipal ordinance that banned the display of signs on residential property, except for signs that fell within specific exemptions. The court held that the ban was an unconstitutional restriction on the freedom of speech.
  3. Metromedia, Inc. v. San Diego (1981): This Supreme Court case involved a challenge to a San Diego ordinance that banned off-premises advertising signs while allowing on-premises signs. The court held that the ordinance was an unconstitutional restriction on free speech, as it discriminated against certain types of speech.
  4. City of Ladue v. Center for the Study of Responsive Law, Inc. (1980): In this Supreme Court case, the court upheld a municipal ordinance that prohibited the display of signs on public property, but only if the signs were posted for longer than 10 days. The court held that the ordinance was a valid time, place, and manner restriction on speech.
  5. City of Boerne v. Flores (1997): This Supreme Court case involved a challenge to a municipal sign code that regulated the size, location, and content of signs in the city. The court held that the sign code violated the Religious Freedom Restoration Act, as it burdened the exercise of religion without a compelling government interest.

ABSTRACT. As a collective, women’s experience in higher education has been disparate and differential to some men’s experience over the last two centuries, fundamentally based on the societal influences of the time. In the formative years of higher education women attended higher education institutions for social stratification reasons or for marital choice opportunities and to a lesser degree for college outcomes. This study’s purpose was to explore the current motivations of freshmen individuals who identified as female undergraduate students in their first year of pursuing a bachelor’s degree in higher education.

This study used a qualitative research design with semi-structured interviews of five undergraduate women at a mid-sized university campus in the Midwest United States. An initial pre-interview questionnaire was given to participants which provided background and demographic information to ensure an illustrative sample of undergraduate freshmen women who were pursuing a bachelor’s degree.

Considering societal changes for the advancement of women using a historical lens, this study used qualitative research methods to articulate what the current motivations and influences are for women who enroll in higher education in contemporary society. By listening to the women’s stories college going was seen as a viable and important next step in their life journey helping them to achieve their personal and professional goals and aspirations. Both K-12 and post-secondary practitioners and administrators can learn through their voices what matters most to them as they seek to fulfill their personal aspirations for a career to make a difference while having a better life not only for themselves but also for those who they plan to influence through their careers and with their future families.

By understanding women’s motivations for higher education credentials, institutional supports can be developed to foster a deeper understanding of women, as students, in higher education. With this knowledge, K-12 and post-secondary educators and leaders can design pre-college academic programs and student support services to facilitate student discovery built on the aspects that motivate female students to pursue the full higher education experience.

“Fish and Chips” | Fred Laidler (1918–1988)

Fish and Chips and the British Working Class, 1870-1930

Fish and chips was in many ways the pioneer fast-food industry.  It became an essential component of working-class diet and popular culture in parts of London, and over wide areas of industrial midland and northern England and southern Scotland, in the early decades of the twentieth century…I propose to argue that the fish and chip trade was not only important enough in itself to justify sustained historical analysis, but also that it provides a useful vantage point for examining important changes in British society more generally.”
