Guest guest Posted October 19, 2006 Report Share Posted October 19, 2006 Hello, in Germany many farmes experienced heavy problems with their pigs and cows, when mobile phone masts did apprear. There was an uproar, and the government did undertake a study (Die Rinder Studie). However, veterinaries and other scientists, who did participate in this study reported, that their findings were misinterpretated, or just left out of the original report. The problems are still there.

Guest guest Posted October 19, 2006 Report Share Posted October 19, 2006 I agree it is vague. I'm not sure what the technical definition for " stray voltage " is. Or what was used as a " Voltage Meter " . My guess is if you walked around various residential areas with the same " equipment " you would have similar findings. I know an apartment I was looking at had very high ELF readings. I did not do further investigation but my guess is there was very poor wiring, grounding and thus " leakage " . So I would say the story was more " vague " than " misleading " . Actually my key point is that these folks were able to 1) show economic harm 2) somehow give evidence of the source (not sure how strong this was) 3) and get a legal finding in there favor If any one is willing to define the what the terms in the article mean scientifically that would be very helpful. I just find the terms " voltage " , " leakage " etc vague. Even though voltage should mean one thing. My 2 cents. Thanks, Alan > >I thought you might find this article interesting.

Guest guest Posted October 20, 2006 Report Share Posted October 20, 2006 Hello Alan, stray voltage is very common. In the USA 70 % of the *null-leader* goes back to the powerplant just through the ground. It is also known with electrical railways, where the phase is coming through the wires overhead the locomotive, but the *null-leader* goes back through the rails. When the rails are not properly grounded, these stray currents pass through the ground via cables, pipes, etc into the houses.

Guest guest Posted October 20, 2006 Report Share Posted October 20, 2006 Hi Alan: Well, let me stress here again, since it seems that some folks may still be thinking -- when they hear the term " stray voltage " -- of EMF fields or E-fields in the air (i.e., free space), that the concept of " stray voltage " refers specifically to small currents, usually 60 Hz AC currents from the power grid (often current which should have been carried back to the power station via the neutral wire or ground wire in the power grid), running through the soil in order to return to the nearest grounded node in that sector of the power grid. If you wish to do a good Google search, there are a number of websites which outline methods commonly used for detecting " stray voltage " in the field, particularly in ag settings. One common method is to employ a digital voltmeter (DVM) with a high impedance input, set to an AC voltage scale which reads from perhaps 0.01 to 2 volts, and then do any of the following (using some long alligator clip leads as needed to span the distance): * measure voltage from a metal fencepost or other type of metal post to another object at least 3 feet away. * stick copper rods or nails about 6 inches long into the soil at least 5 feet apart, and monitor voltage across them However, such measurements can be very tricky, and are fraught with false readings, and, even under best conditions, the wires (to the meter) must be left lying flat on the soil during measurements. If the DVM is too sensitive, the wires running across the surface of the soil may act as antennas and pick up AC or RF signals (EMF or E-field or H-field) from the ambient airspace, and, via induction (or even capacitive coupling, if the two probes are not firmly " grounded " ...), may incude false and misleading readings. And, there are other red herrings which can confuse the casual observer as well, since it has been well-known for many hundreds of years that the earth itself often generates sizeable DC electric currents which flow from point to point through the soils and strata at the earth's surface (these have sometimes been called " earth currents " or " telluric currrents " , and the earth itself can even generate low-frequency AC currents in the ELF, VLF, and even LF region; the AC and DC currents are due largely to geophysical phenomena (including soil and rock electrochemistry, activity of oxidizing or reducing microbes (i.e., " redox activity " ) in the aquifer or " water table, " and piezoelectric activity of large masses of stressed rock. with care, --Vinny At 01:47 AM 10/20/2006, you wrote: >I agree it is vague.

Guest guest Posted November 15, 2006 Report Share Posted November 15, 2006 " Stray voltage " is a term concocted by the electric utility companies and the Public Service Commissions in the American midwest. To cover their legal butts. Electricity does not stray! Current is on the ground because the utilities are using the ground to return most of the current to their substations. They took great care to define " stray voltage " as being " steady state. " In other words, just 60 Hz. Where can anybody find current that is pure 60 Hz these days? Also, they define " stray voltage " as only affecting animals. Thus, even if the same thing harming his cattle destroys the farmer's health, he has no case, because " stray voltage " does not affect people - by definition. It is all crooked politics. It is rare indeed for a dairy farmer to be able to win a case. And rarer yet to every collect any of the money! So far, no lawyer has been found to take a human injury case to court. Several times a lawyer began to prepare such a case, but each time suddenly the lawyer was doing some kind of work for the utility company instead. They pay really well.

Guest guest Posted November 16, 2006 Report Share Posted November 16, 2006 Actually, it must be admitted that the term " stray voltage " is over 100 years old (certainly in the UK). It was found that with the first electrified London Underground lines, the voltage/current returning through the ground affected buildings, pipes and businesses (even in those days!) and they had to put in an extra rail to act as an earth return. This was not required on main lines outside London, which returned current through the earth (and still do). However, these are dc voltages. Most electrified railways nowadays are ac but have earth return. All the same, if farmers' cows stray, they can be liable for any damage caused (again, at least in the UK) so maybe stray voltage isn't such a bad term after all!

Guest guest Posted November 18, 2006 Report Share Posted November 18, 2006 Hi Shivani and folks: I noted with interest that you recently wrote the following in your reply to another poster on this list group: >Shivani replies: > The corect technical term is " ground current. " >Shivani replies: > Cows stray. Dogs and cats stray. Electrical current does not. You are certainly entitled to your own opinion and beliefs, and I have no desire to convert you to my opinion(s), but, since you have raised this issue about stray voltage repeatedly, I choose to share briefly my observations and opinions as an electrical/electronics engineer and scientist: On " Ground Current " First, while one correct term for the phenomena would indeed be " ground current " , we must understand that the term ground current is very broad umbrella term, and it includes all kinds of DC and AC (at any of many frequencies ranging from ULF to UHF frequencies) currents flowing in the ground from both natural (i.e., from geological, geophysical, geobiological and planetary atmospheric sources; some of these natural electrical current flows have been called " telluric currents " by some authors) and also manmade sources. So, it is kind of like saying that a Toyota Corolla is an " automotive vehicle " -- yes, it is, but, more specifically, it is a car or an automobile, and more specifically, a Toyota brand car, and even more specifically a Toyota Corolla. And, to me, this term " ground current " is just one of several correct terms used at times to denote such phenomena, but it is a very broad umbrella term, and, when using it, one would usually need to specify further what type or species of ground current to which they were referring. On " Stray Voltage " I disagree that electromotive potential (often called " voltage " by laypersons) and current do not stray. My experience, after having worked closely for much of the past fifty years with various types and forms of electricity ranging from DC through ULF, ELF, VLF and on up to UHF and beyond -- including various types of ground currents of both natural and manmade origin -- is that electric potential and current can each easily " stray " , and for many reasons. Any electronics engineer who designs circuitry knows that currents will find the darndest and most unexpected paths to return to " home " , and both electromotive potential and electrical currents in one place can induce other EM potentials or currents even at a modest distance in another place. For one great but extreme example of stray current in nature, consider lightning as it finds its path through the air and particularly as it nears the ground -- it zigazgs wildly, and often the current path, as it nears the ground, breaks off into dozens or hundreds of unpredictable fractal geometries. Another example is corrosion caused to buried metal pipes and parts due to naturally-occurring DC and ULF currents. Further, as any ship designer or shipyard worker knows, there are even plenty of natural " stray currents " which occur in the oceans and which cause corrosion of below-water metal components (such as metal hulls) of ships; and these natural " stray " currents existed in the seas for many millions of years before humans ever appeared on earth. So, to me, the terms " stray voltage " , or more accurately, the two mutually-complementary terms " stray electromotive potential " and " stray current " are quite valid descriptors -- albeit rather broadband and generalist designators -- of real and valid phenomena. It is also worthwhile to note, much as I have noted above for the term " ground current " , that the terms " stray voltage " , " stray electromotive potential " and " stray current " are all broad terms, and can actually describe a wide range of natural and manmade phenomena. A Few Words About the Terms I understand that much of your fire and ire about the widespread usage in the popular vernacular of the term " stray voltage " stems from the fact that you believe that the widespread usage of term for leakage current from AC power distribution systems can somehow contribute to allowing utility companies to " wriggle out " of responsibility for significant harm caused by AC power distribution system ground return currents which should better be returning via the neutral wire or the ground wire. However, I suspect that any immunity that many utility vendors may seem to enjoy from liability for damage from such currents is due far more to their vast legal funds and large teams of litigation attorneys than to the usage of the term " stray voltage " , which has been in the popular venacular for over a hundred years. Lastly, I must note as an observer that many of your writings about this topic and the topics of EMF effects upon humans and animals seem to be tinged with quite a bit of stridency, anger and bitterness (indeed, you have actually used the term " bitter " at times in your posts to the list group.) It is my observation that those phenomena in the outside world which we continue to hate, or blame, or feel bitter about, in other words, those things against which we rail and struggle and which we resist, tend to propagate and expand even more in our lives as time passes, due largely to our own resistance, as we end up becoming co-creators of those things which we resist. Thus, it may be understandable that such EMF-related phenoma appear to continue to cause you grief and strife in your life. with care, --Vinny At 11:09 AM 11/17/2006, you wrote: >Ian wrote: > > Actually, it must be admitted that the term " stray voltage " is over 100 >years old (certainly in the UK).

Guest guest Posted November 19, 2006 Report Share Posted November 19, 2006 Shivani replies: The corect technical term is " ground current. " Let's be precise; one currently used and acceptable technical term is ground current. Another term describing similar phenomena, in use before any of us was born, is stray voltage. Both terms have " loose " or " vernacular " descriptions, and also one (or more) " precise " technical definitions - since unfortunately in many areas, definitions vary between disciplines and countries. However, " stray voltage " is not a term recently coined by US Midwest utilities, unless they are capable of working at more than the speed of light and putting it into books published 40/70 years ago :-) Ian _____ From: [mailto: ] On Behalf Of SArjuna@...

" The present electrical transmission is incapable of returning all the current to the substations, because it was never designed to handle the high-frequencies that are added to it by the users along the way. In the part of the US where I live, 70 to 80% of the return current travels via the ground (terra firma/dirt) all the way to the substations. High-frequency electricity behaves differently from 60 Hz. It is subject to the " skin effect, " which describes how it tends to flow away from wiring and flow over the surfaces of of things, including the ground. In some places, there are invisible flows of current as much as 100 feet wide, flowing over the ground. Too bad if your livestock happen to be in such an area. Or your house.
