Abstract

A clamp-on measurement device, for attachment to a support, with at least one instrument transformer, a retaining device for holding the instrument transformer and a fastening device (4) for attachment of the retaining means to the support. The retaining device can be attached to the fastening device (4) such that the retaining device can be moved in at least one predetermined direction away from or toward the support and can be pivoted along a pivot axis which runs preferably perpendicular to the predetermined direction. This results in the clamp-on measurement device, after attachment to a support, being easily disengaged from the support for maintenance and repair purposes and then can be reengaged with the support without losing its original alignment.

Clamp-on measurement device, for attachment to a support, comprising:

at least one instrument transformer,
a retaining means for holding the instrument transformer, and
fastening means for attachment of the retaining means to the support,
wherein the retaining means is attachable to the fastening means in a manner enabling the retaining means to be movable in at least one predetermined direction toward and away from the support and to pivot about a pivot axis,
wherein the attachment of the retaining means to the fastening means enables an instrument transformer held in the retaining means to be both move away from the support pivoted around the pivot axis in a manner exposing a side of the instrument transformer which had faced the support beforehand, and
wherein the attachment comprises a groove on one of the retaining means and the fastening means which runs in the predetermined direction and a projection on the other of the fastening means and the retaining means which engages the groove to ensure movement of the retaining means toward and away from the support and the pivoting motion of the retaining means around the pivoting axis.
