摘要： The present invention relates to the shielding of clamps of a transformer, and in particular to an electric shielding arrangement for a transformer and a transformer with the arrangement. An electric shielding arrangement for a transformer (101) is provided, with a clamp (102, 130, 132) attached at a yoke (109, 124, 126) and stabilizes the yoke (109, 124, 126) of the transformer (101). The arrangement comprises an electric shielding device (100, 140, 142) arranged at the clamp (102, 130, 132) between the yoke (109, 124, 126) and a winding (103) of the transformer (101) and having a trough- like form. The electric shielding device (100, 140, 142) may have the form of a rounded cover and is adapted for shielding the clamp (102, 130, 132) from an electric field of the winding (103).
