The aim of this work is to present a novel and compact magnetic field source designed to test the performances of electromagnetic shields. To date, there is no well-defined procedure to evaluate the shielding capabilities of these systems. For this reason, a method is proposed in this paper in which an artificial source generate a magnetic field in all three dimensions, to evaluate the shielding factor (SF) of the enclosure of a 630 kVA cast resin transformer. This system compared to mono or bi-axial sources allows to better evaluate the SF of the object under examination. The triaxial coil source was made using the fused deposition modeling (FDM) technology using PLA material for the supports. This allows for a lightweight and portable object to be made.

Abstract
The aim of this work is to present a novel and compact magnetic field source designed to test the performances of electromagnetic shields. To date, there is no well-defined procedure to evaluate the shielding capabilities of these systems. For this reason, a method is proposed in this paper in which an artificial source generate a magnetic field in all three dimensions, to evaluate the shielding factor (SF) of the enclosure of a 630 kVA cast resin transformer. This system compared to mono or bi-axial sources allows to better evaluate the SF of the object under examination. The triaxial coil source was made using the fused deposition modeling (FDM) technology using PLA material for the supports. This allows for a lightweight and portable object to be made.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
