Equipotential Grids Required by the NEC - Are they Useless?

 

ImageThe following paper describes Stray Voltage Service’s www.strayvoltage.ca approach in dealing with farm neutral to earth voltage. They have tested over 2,500 farms for stray voltage and this maybe more than any organization has done. The approach they offer provides real world low cost technical solutions to stray voltage in two broad ways; first by balancing secondary farm neutral loads and then secondly by reducing the remaining non-engineered electricity paths from passing through farm animals. This paper identifies the technical failures of the past and current standard stray voltage mitigation techniques and its outcomes. This paper describes some impressive results offered using our remote monitoring oscilloscope services to farmers across North America and the world.

  • They're more than useless. They are dangerous as they are causing a dc component voltage to always be present under the cows from the constant charging of the different metals by the ever present utility neutral current flowing over the bonded floor back through the barn into the main service ground and back to the grid. We need isolation from the utility neutrals before metal will work in the floor. We may need to go to a fibermesh rebar system instead.
