The aim of the work is the achievement of a level of magnetic induction lessthan 3 μ T all around the substation, even very close to the wall of the substation under rated conditions. The second, butno lessimportant, goal is the choice of the shielding geometry in order to reduce the amount of necessary material. In this regard, more than one configuration has been analyzed and compared with the other ones. The focus is on passive shielding techniques, based on the use of two kinds of material, conductive and ferromagnetic. In particular, the shielding solution is based on the installation of sandwich ferromagnetic-conductive plates on the ceiling and/or the walls of the substation, so that every wall or some of them are shielded completely or partially, depending on the configuration of the substation. The proposed solution has been tested on a substation composed by a cast resin transformer 630kVA and an opportune configuration of conductors which can simulate the effect of the busbar of a L V switchgear. Different configurations of the shielding plates have been tested (walls completely shielded, walls partially shielded, etc.) in order to minimize the use of material. Finally is important to point out that this technique can be implemented also on a working substation (e.g. by installing the plates externally).
