Abstract

In this study, the EM fields produced by high power 3-phase transmission lines are investigated. The dependence of the magnetic field with respect to vertical and horizontal distances from the transmission lines are illustrated and the minimum distance from the lines for human safety is specified according to ICNIRP standards. In addition, a quasi-static examination to the magnetic shielding of several enclosures are performed. In the analysis, the integral form of Maxwell´s equations with boundary conditions are used to derive the shielding effectiveness (SE) equations. An experiment is carried out to verify the validity of the theory developed for magnetic fields of transmission lines and the SE provided by the building. An excellent agreement is obtained for experimental and theoretical results.
