Sati Shielding S.r.l. boasts an extensive, ten-year experience and thorough knowledge of the sector, and is able to supply standard as well as innovative solutions to suit the customer's special requirements.
Sati Shielding S.r.l. is able to deal with large and small customers, and is able to manage small and large electrical infrastructures (from small LV systems, cable lines, small devices, to the extensive overhead and cable HV lines).
At the end of the environmental impact stage or after a measurement survey, in the event of finding the legal limits or limits set by suitable specifications defined by the customer have been exceeded, it is possible to design mitigation solutions that reduce magnetic induction levels.
Through its Engineering department, Sati Shielding S.r.l. is able to design passive, active or miscellaneous mitigation systems for human protection or to assure immunity of electronic devices and systems.
The design and construction of a shielding system is similar to "tailoring" and in order to meet certain magnetic fields reduction objectives it requires the shape, dimensions and thicknesses of the shielding solutions to be chosen so as to optimise the amount of material according to the area to be shielded and according to the sources (e.g. position and power of the various components).
A shielding design and construction project is provided by way of example, which shows how design is able to accurately foresee the reduction of magnetic induction levels when the mitigation system is installed.
Fig. AA shows the case of shielding a building located underneath a HV overhead power line. The shielding (Fig. BB) features openings at the windows, assessed in the design stage. Fig. BB shows the designed shielding model indicating the floor where magnetic induction is assessed (it must be lower than 3 μT).
Fig. CC shows the colour map of magnetic induction before and after the implementation of the shield, which evidences the reduction effect introduced by the same.
Fig. DD shows the shielding system during its installation while Fig. EE shows the magnetic induction levels measured after the mitigation operation; these levels show optimal consistency with the design specifications (Fig. CC).
