Abstract

See full text

An open-loop electrical current transducer for measuring an electrical current flowing in a primary conductor, includes a magnetic circuit core with an air-gap, and a magnetic field sensing device positioned at least partially in the air-gap, the magnetic field sensing device including a circuit board, a first magnetic field detector in the form of an ASIC mounted on the circuit board, and a second magnetic field detector in the form of a conductive pick-up coil formed on two or more layers in or on the circuit board. The outputs of the first and second magnetic field detectors are connected to a signal processing circuit generating an output signal representative of the electrical current, the output of the ASIC representing a low frequency (LF) channel and the output of the pick-up coil representing a high frequency (HF) channel.
