Analysis of magnetic fields produced far from electric power lines

The authors develop a simple and general method for analyzing the magnetic fields produced by power lines at far distances, that is, at distances large in comparison to the spacing between the line's phase conductors. Magnetic fields produced far from conventional power lines have remarkably si...

Description
Summary:The authors develop a simple and general method for analyzing the magnetic fields produced by power lines at far distances, that is, at distances large in comparison to the spacing between the line's phase conductors. Magnetic fields produced far from conventional power lines have remarkably simple properties. Formulas for the fields produced by various conventional and unconventional power line configurations are presented. Included are line designs characterized by reduced magnetic-field levels. Errors in the formulas are less than +or-10% at the edge of a typical transmission right-of-way.< >
