DEVICE AND ASSEMBLY FOR MEASURING ELECTRIC CURRENT Russian patent published in 2016 - IPC G01R11/00 

FIELD: electricity; measurement equipment.

SUBSTANCE: present invention relates to metrology, particularly to the means of measuring current magnitude. Proposed device comprises a means for fastening a flexible Rogowski coil configured to be in an open position that allows installation around the cable, and a closed position to cover the cable, as well as the activation device configured in such a way that the coil can move from one position to another. Coil is mounted on a support, which is formed by a flexible channel attached to the jaws. Device also includes a return spring, spacers and a magnetic circuit. Jaws can pivotally turn on the anchor, which is connected to the activation device rod. Translatory motion of the rod drives the rotary motion of each jaw. Hinged axis on the anchor is shared by both jaws. Jaws are also equipped with pins arranged in an opening on the anchor, and connected to each other by a spring. Device also has a slider and a centering spring.

EFFECT: to simplify the measurement procedure.
