Donald W. Zipse, P.E. has been involved in stray current, the correct term for stray voltage since 1970 when he presented his first technical IEEE paper. Since then he has present many papers on stray current, which is dangerous and hazardous.
He would be willing to talk to said reporter and give him the FACTS. He has been involved in stray current cases from New Jersey to Oregon.
As long as the utilities continue to use the multigrounded neutral distribution systems there will be dangerous and hazardous stray current flowing uncontrolled over and through the earth and the paths that this stray current takes on its way back to the substation cannot be controlled as it will flow over the earth, underground metallic pipes, etc. In addition, the bare concentric neutral direct buried cable is also a root cause of stray current. In one case approximately 5 cows were dying per day for over a year before the cause was found in a herd of 3,000 cows.
Mr. Lawrence C. Neubauer has discovered a dc component to stray current when it flows through re-bar in concrete so that cows and humans in swimming pools get a double whammy, both ac and dc shocks.
We have been involved in many cow cases and I have been involved in human cases also with stray current emanating from the utilities distribution systems. Humans can be hurt from using swimming pools, showers, hot tubs, etc. The National Electrical code is deficient in that the code allows and requires multiple grounding of the neutral allowing the earth to become a parallel path for the neutral current. This parallel path allows cows and humans to get electrical shocks.
The problem is the utilities have unlimited funds and in the case of Idaho when the utility lost a case to the tune of $ 17.5 million to the dairy farmer, the utility went to the legislature and got a law passed to protect the utility from being sued.
Watch for a forth-coming book about a dairy farmer and stray current.
Would be glad to talk to said reporter.
