A Shielding System Proposal for the Cabling of Electric Glass Melters

Abstract

This paper analysesthe impact on workers of the electromagnetic field produced by large furnaces for glass production. The paper also propose a solution for the reduction and the containment of magnetic induction levels below the limits imposed by national and international directives. Using a three-dimensional numerical calculation code based on the hypothesis of filiform conductors in the air (Biot-savart law). The choice of the solution is based on the technique named highly coupled magnetically passive loop technique (HMCPL). The solution was then implemented and a comparison between the magnetic induction values before and after the installation of the shielding solution is presented.
