Abstract (en)
The invention relates to the electric shielding of yokes of a transformer, and in particular to a yoke and electric shielding arrangement for a transformer and a transformer with the arrangement. An electric shielding arrangement for a transformer is provided with a yoke (109, 301) for connecting limbs (113) of the transformer (101) and an electric shielding device (112, 301). The electric shielding device (112, 302) is arranged at the yoke (109, 301) between the yoke (109, 301) and a winding (103) of the transformer (101). The first electric shielding device (112, 302) may be a rounded cover (112, 302) and is adapted for shielding the yoke (109, 301) from an electric field of the winding (103) thus smoothing an electric field.
