This paper proposes a mathematical model of electric and magnetic fields caused by high voltage conductors of electric power transmission systems by using a set of second-order partial differential equations. This study has considered the effect of conductor phase-sequence orientation on electromagnetic fields emitted around a double-circuit, extra high-voltage, power transmission line. Five ty...

Results are presented on the optimization of the electric field distribution obtained during Transcranial Magnetic Stimulation (TMS) for deep neuron stimulation by using the Continuum Design Sensitivity Analysis (CDSA) combined with a commercially available generalized finite element code (OPERA). In order to obtain a magnetic field that can penetrate deeply and safely to activate the brain’s c...

Ground level magnetic field from overhead transmission lines (OHTLs) is of increasingly important considerations in several research areas due to their harmful effect on human health and environment. This paper computes the ground level magnetic field, under normal and abnormal conditions of Egyptian 500-kV single circuit transmission line, in three dimension (3-D) coordinates by using 3-D inte...
