Abstract

The invention relates to an insulator, such as a bushing insulator, which comprises a body (1) made of an insulating material, an opening for receiving a primary current conductor (2), a Rogowski sensor (3) arranged around the opening and a screening cover (5) which is made of a conductive material, receives windings or coils (4) of the Rogowski sensor and is arranged to form a loop with a closed cross section, characterized in that the screening cover (5) is provided with at least one ear (8) for receiving a fitting part (6), which is used to support the screening cover in place.
