COMPUTATION OF ELECTROMAGNETIC-FIELDS PRODUCED BY ELECTRIC-POWER LINES AND RESIDENTIAL ELECTRICAL WIRING

Recent epidemiological research work suggesting a link between 50-60 Hz magnetic fields and certain forms of leukemia and brain cancer, has dramatically increased interest in evaluating electromagnetic fields emanating from a three-dimensional arbitrary network of energized overhead and buried conductors. This article presents electric and magnetic fields inside and outside an imaginary house located near a power distribution line. The electromagnetic fields are computed using a powerful frequency domain method described in a companion publication. Since the main objective of this work is to illustrate the usefulness and capabilities of the analytical method used for the computations, the emphasis here is on modelling complex portions of residential electric circuits, buried water pipes and ground rods, without necessarily duplicating an existing house or experimental equivalent. This approach was adopted deliberately. Future work will focus on modelling existing sites for which a complete set of experimental data is available.
