A measuring transformer for use with high-voltage switch-gear of a type which employs metal encapsulation. The transformer is retained between flanges at a joint of the metal encapsulation and includes a sealing and insulating spacing means. The latter forms a ring-shaped cavity with the flanges and seals such cavity from the interior of the metal encapsulation. In the ring-shaped cavity is disposed at least one iron core having a secondary winding placed thereon, the latter core together with the inner conductor of the high-voltage switch-gear forming a current transformer. |
