Abstract

The transmission lines are equipment that emit high-intensity magnetic eld due to their high
currents. Such magnetic elds can be harmful to health and cause interference in electronic devices. This paper
presents a methodology to minimize the magnetic eld emitted by transmission lines at ground level. For this,
the magnetic eld is calculated based on the electromagnetic analytical model and optimized by a stochastic
method known as Dierential Evolution (DE). The penalty method is considered for the treatment of problem
constraints. To show the DE robustness, the results are compared with a well-established optimization method,
the Genetic Algorithm (GA).
