This paper calls attention to a continuing and growing problem concerning an ever-present electrical hazard that is being swept under the rug. Several miscalculations and lack of understanding of grounding have combined over the past 80 years to set into motion the electrocution of dairy cows, pigs and humans residing in North America from the electrical distribution system. The urge to reduce costs...
Misunderstandings concerning stray current and equipotential planes are prevalent in North America. Clarification of and differences between equipotentials found in high voltage cable and in concrete encased reinforcing bar installations in concrete pads and swimming pools are explained. Misunderstanding and false interpretation of the IEEE Standard 80, ldquoGuide for Safety in AC Substation Groundingrdquo...
Modeling NEV issues requires the most detailed circuit models for distribution system analysis except for, perhaps, lightning surge protection analysis. A proposed line model benchmark is solved and results reported. Modeling NEV will become an increasingly important problem. Based on the proliferation of harmonic producing loads in residential environments, the amount of triplen harmonics will tend...
The Distribution System Analysis Subcommittee (DSASC) has defined a simple test case for neutral-to-earth voltage calculations. This paper presents a solution in the Alternative Transients Program (ATP), with illustrations of both ldquostray voltagerdquo and ldquotemporary overvoltagerdquo. With scripting, stream-oriented editing, and text processing, the ATP may be used to perform sensitivity studies...
