Abstract
The work presents a procedure to optimise a mixed passive and active shielding. The shielding concerns a building in proximity of a high voltage overhead line. This condition often arises in the reality. For Italian legislation, if the building is located at a distance that does not guarantee the respect of the limits on the magnetic flux density, the use of such building is not authorised for stays longer than 4 hours per day. In the case of overhead lines, the line operator can install a shielding acting directly on the source at the cost of difficult and expensive modifications to the pylons. The most feasible solution is to perform a shielding of the building which is generally passive and very rarely active. The selection of one or the other type of shielding is generally linked to factors external to the purely technical ones. This paper presents an optimised design of a shielding based on the use of both technologies. The search of the optimal condition has been based on performance parameters not considering cost constraints. The work presents two study cases characterized by different distances of the building that has to be protected from the power line.
