The Confusion Surrounding “Stray Voltage”


 

ImageWhile “stray voltage” has been a concern for farm livestock for many years, it is only within the past few years that the term has been associated with human fatalities. The industry has seen an expansion of the term’s usage to describe events that some engineers feel is incorrect. This situation has resulted in costs to utilities exceeding many millions of dollars that has a questionable impact on customers increased safety.

 

The purpose of this paper is to discuss the confusion that now exists in the area of “stray voltage”. The paper will discuss the traditional definition of the term “stray voltage”, as well as the recent usage of the phrase to describe more dangerous conditions such as step-and-touch voltages, temporary overvoltages, contact voltages, etc. Finally, the paper will address the status of the industries response to this issue. It will discuss the measures taken by some utilities as well as the IEEE to establish some sort of industry guidelines to address these issues.

  • Everyone,

    Jim was kind enough to speak with me directly and very candidly on the issues of stray voltage and his paper.

    I believe Jim is an honest and extremely gifted electrical engineer and is rightfully concerned with safety, as we all are. He is also in a position to help clarify the "muddy waters" of miss-information as part of the IEEE Stray Voltage Working Group.

    Jim has offered to keep an open mind and review the papers and studies that may well have been used in a manner not consistent with the “Original” published results. There are numerous documents that have been rewritten and re-published, by others, omitting the true results, of the original work and then came to an extremely different opinion, which tends to support their present position.

    Here is the challenge for all participants in this forum, kindly submit your comments citing the original research and the results of that original research results and not the published documents that are from a review of the original research. There are far too many papers that are unfortunately considered "NEW" research when, in fact, they are stating entirely different conclusions from the research actually conducted.

    Personally, I have accepted Jim's offer to provide him with copies of the original papers that I have possession of and will proceed to do so. If someone has a PDF for USDA 696 please send it to Jim or me and we will have an extremely good start at clarifying the "Muddy Waters" concerning stray voltage and the new opinions of persons that simply reviewed original papers and came to a different conclusion that supports their "NEW" position.

    Please consider helping Jim to be able to form his own opinions, from his review of original papers.

    Jim, if I have miss-stated anything please respond and thank you!! chuck
