Abstract (en)

[origin: WO2009144759A1] An optimized shielding transformer (1), in particular for carrying out dielectric tests, comprising a containment case (2) which is placed on a support structure, a magnetic core (3) positioned inside the containment case (2), a primary winding (4), coupled with the magnetic core (3), and a secondary winding (6) magnetically coupled with the primary winding (4) through the magnetic core (3). The transformer (1 ) includes a shaped protection screen (8), facing the primary winding (4) and provided with a metallic outer surface (8a) which splits up in uniform and capacitive way on the primary winding (4) a possible voltage impulse which affects the shaped screen (8) itself.
