Electrical current transducer

摘要

An electric current transducer (1) includes a magnetic core (2) made of a highly magnetically permeable material encircling a central passage (16) configured to receive a primary conductor, and a magnetic field detector (4). The magnetic core (2) comprises a slot (10), and the magnetic field detector comprises a sensing portion inserted in the slot (10). The slot (10) extends completely through the magnetic core from a radially outer side (12) to a radially inner side (14) and is oriented such that at least a portion of the magnetic core (2) forms an uninterrupted closed loop around the central passage.
