More Information
Summary:The present disclosure relates to a Pulsed Eddy Current (PEC) system comprising a transmitter (2) configured to generate a changing electromagnetic field which induces eddy currents in an object of an electrically conductive material arranged within the electromagnetic field. The transmitter comprises a switching device (24) and a transmitter coil (21) configured to be connected to a voltage source (25). The switching device is arranged for switching a current generated by the voltage source through the transmitter coil. The transmitter coil comprises a plurality of parallel electrically conductive coil layers (22) with a respective damping resistor (23) connected across each of the coil layers (22), each of the coil layers being connected in series with a respective diode (D).
