Guide for Animal Deterrents for Electric Power Supply Substations

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.

Dogs and Agriculture

Dogs have been bred for a variety of purposes throughout history, including as working animals to support agriculture. Dogs have been bred for specific traits that make them well-suited to work on farms, such as intelligence, obedience, strength, and endurance*.

History and ArchitectureUniversity of Oxford Estates Services

Supported by funding from the European Research Council and the Natural Environment Research Council, a large international team of scientists compared genetic data with existing archaeological evidence and show that man’s best friend may have emerged independently from two separate (possibly now extinct) wolf populations that lived on opposite sides of the Eurasian continent.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

* Here are a few examples of how dogs were bred to support agriculture:

Herding dogs: Dogs such as the Border Collie, Australian Cattle Dog, and German Shepherd were bred to help farmers manage livestock by herding them from one place to another. These dogs have a natural instinct to gather and control herds of animals, and they can be trained to respond to a farmer’s commands.

Hunting dogs: Many breeds of dogs, such as the Labrador Retriever, were originally bred as hunting dogs to assist farmers with hunting game for food. These dogs have a keen sense of smell and are skilled at tracking and retrieving prey.

Guard dogs: Certain breeds of dogs, such as the Great Pyrenees, were bred to protect livestock from predators such as wolves and bears. These dogs are fiercely protective of their flock and will guard them from any perceived threat.

Draft dogs: Some large breeds of dogs, such as the Bernese Mountain Dog and the Saint Bernard, were bred to pull carts and wagons on farms. These dogs are strong and muscular and can move heavy loads across long distances.

Overall, dogs have been bred for centuries to support agriculture in a variety of ways. Their intelligence, loyalty, and hardworking nature have made them invaluable assets to farmers and have helped to shape the course of human history.

Stray Voltage: Sources and Solutions

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.

City Chickens 101

There are a few campuses in the USA and UK where chickens are allowed to roam freely, often as part of educational programs or sustainability initiatives.

In the USA, some examples include:

University of California, Davis: The campus has a farm that includes free-range chickens as part of its agricultural programs.
Bard College: They have a farm that features free-range chickens, contributing to their sustainable agriculture practices.

In the UK, examples include:

University of Edinburgh: They have had initiatives where chickens roam freely as part of urban farming projects.
Kingston University: Their campus has included chickens in community gardening efforts.
These programs often emphasize sustainability, education, and the benefits of local food production.

Small scale chicken farming, as in residential and even in educational settlements, are regulated at the local level by municipalities, cities, or counties. Local ordinances vary widely with some common elements including:

  1. Zoning Laws: These laws determine whether residential areas can keep chickens and in what capacity. Some areas may prohibit chickens entirely, while others may allow a limited number.
  2. Permit Requirements: Some localities require residents to obtain a permit to keep chickens.
  3. Coop Specifications: Regulations may include specific requirements for chicken coops, such as size, location, and sanitation standards.
  4. Noise and Nuisance Laws: Rules may be in place to manage noise and odors, ensuring that chickens do not become a nuisance to neighbors.
  5. Health and Safety Codes: These codes can cover the cleanliness of the area where chickens are kept, as well as guidelines for feeding and waste disposal to prevent attracting pests or creating health hazards.
