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.

2022 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.

The Ethics of Farming Animals

“The Peace of Wild Things”

When despair for the world grows in me
and I wake in the night at the least sound
in fear of what my life and my children’s lives may be,
I go and lie down where the wood drake
rests in his beauty on the water,
and the great heron feeds.

I come into the peace of wild things
who do not tax their lives with forethought
of grief. I come into the presence of still water.
And I feel above me the day-blind stars
waiting with their light. For a time
I rest in the grace of the world, and am free.

— Wendell Berry

Guidelines & Standards

Permits and Permissions: Researchers should obtain the necessary permits and permissions required for conducting bird research, especially if it involves capturing, banding, or handling birds. These permits are often issued by relevant government agencies responsible for wildlife management or conservation.

Bird Banding and Marking: When capturing and marking birds for scientific purposes, researchers should follow established protocols, such as those recommended by the Bird Banding Laboratory or other authorized organizations. This includes proper handling techniques, banding procedures, and data recording.

Ethical Considerations: Researchers must ensure that their studies are conducted in an ethical manner, taking into account the welfare of the birds and minimizing any potential harm or stress. Ethical considerations may include avoiding excessive disturbance, minimizing handling time, and assessing the potential impacts on breeding, nesting, or migratory behaviors.

Field Techniques: Researchers should be proficient in field techniques specific to bird research, including bird identification, behavioral observations, and survey methods (e.g., point counts, transects). Standardized protocols are often available for different types of bird research, such as breeding surveys, migration monitoring, or population assessments.

Data Collection and Analysis: Scientists should follow rigorous data collection protocols, ensuring accuracy and consistency in measurements, observations, and data recording. Proper documentation of field notes, metadata, and photographs is crucial for data integrity and reproducibility. Data analysis should adhere to established statistical methods and appropriate modeling techniques.

Habitat Conservation and Protection: Researchers should be mindful of the potential impacts of their activities on bird habitats and ecosystems. They should follow guidelines for minimizing habitat disturbance, preventing the spread of invasive species, and promoting conservation principles. This may include habitat restoration, nest box management, or collaborative efforts with local conservation organizations.

Collaboration and Data Sharing: Scientists are encouraged to collaborate with other researchers, organizations, and citizen science initiatives to enhance data sharing and contribute to broader bird research and conservation efforts. Sharing data through platforms like eBird or contributing to regional bird atlases can provide valuable insights into bird populations and distributions.

These are general considerations, and it’s essential to consult the most up-to-date guidelines and resources from reputable sources such as ornithological societies, bird research institutions, or government agencies dedicated to wildlife management and conservation in your specific region or country.
