Abstract: A detector for detecting at least one electric quantity in an electric conductor, and an overhead network for distributing electricity. The detector includes a frame on which a mechanism is fixed, the mechanism including a magnetic toroid, divided into two branches rotatable around an axis defined by the frame, between a separated position and a position closed around the electric conductor, a current sensor, divided into two branches rotatable around an axis defined by the frame, between a separated position and a position closed around the electric conductor, the current sensor performing an AC current measurement, a force transmitting element transmitting a rotational force to the magnetic toroid and the current sensor, the element being provided with at least one portion to receive the conductor by bearing, and a first clamp including two clamp arms, and a second clamp including two clamp arms.

Abstract: This detector (1) for an electric conductor comprises a frame (2) on which a mechanism unit (200) is fixed including a magnetic toroid, divided into two branches, the toroid having a coil (24) wound around at least one of the two branches, and a current sensor, divided into two branches (26A, 26B). The mechanism unit also includes a force transmitting element, said element being provided with at least one portion able to receive the conductor by bearing, and at least two clamps (30A, 30B) for anchoring the detector on the electric conductor, each clamp being rotatable between an open position and a locked position of the clamp. The detector also comprises a base and at least one electronic device (6). The force transmitting element is extended by a trigger, each anchoring clamp (30A, 30B) has a portion in contact with the trigger, and each clamp bears a protruding member (34A, 34B). A spring (36A, 36B) is stretched between the protruding member (34A, 34B) and a part (290B, 290B) fixed on the frame (2).
