Abstract: The present disclosure provides for the shielding of clamps of a transformer, and including an electric shielding arrangement for a transformer and a transformer with the arrangement. An electric shielding arrangement for a transformer is provided, with a clamp which is attached at a yoke and stabilizes the yoke of the transformer. The arrangement includes an electric shielding device arranged at the clamp between the yoke and a winding of the transformer and having a trough-like form. The electric shielding device may have the form of a rounded cover and is configured to shield the clamp from an electric field of the winding.
