Current sensor has a loop of a rogowski and method of manufacturing such a current sensor

摘要

This current sensor (16) to a loop of a rogowski is intended to measure a current flowing in an electrical conductor. The current sensor comprises a main winding (22) which comprises two ends (42, 44), a closing mechanism (20) which is adapted to connect one end (42) to the other end (44). The closing mechanism is movable with respect to one of the ends (44) between a closed position and an open position. The two ends (42, 44) are, in the closed position of the closing mechanism, which are arranged along the longitudinal axis (x) of the closing mechanism (20) and spaced from one another along the longitudinal axis (x). The sensor further comprises a secondary winding (32) disposed between the ends (42, 44) of the main winding (22), in the closed position of the closing mechanism (20). The secondary winding (32) comprises a plurality of turns offset with respect to each other along the longitudinal axis (x).
