A current sensing circuit is provided for measuring a current in an electrical line connecting an electrical supply to a load. The current sensing circuit includes a magnetic circuit having: a magnetic core, a reference winding wound around the magnetic core, and a conductor passing through center of the magnetic core. The conductor is being connected to the electrical line. The current sensing circuit further includes a detection circuit connected to the reference winding of the magnetic circuit. The detection circuit is configured to detect a change in condition of the magnetic core and generate a detection signal in response to determination of the change. Furthermore, the current sensing circuit includes a controller coupled to the detection circuit for receiving the detection signal. The controller measures the current in the electrical line in response to the detection signal from the detection circuit.
