In this papera solutions for shielding a MV /L V substation is presented. 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).
