Abstract
A device () for detecting and processing signals relating to partial electrical discharges in an electrical apparatus () powered by a square-wave () voltage modulated by a modulating wave () in such a way as to form an alternating voltage of predetermined frequency, comprises: a sensor () connectable to the apparatus () for detecting a discharge signal () representing the electrical pulses generated by the partial discharges; a processing unit () connected to the sensor () to receive the discharge signal () and derive the detection instants of each of the pulses detected with respect to a predetermined time reference, a synchronization module () designed to receive an electrical signal () representing the power supply voltage and equipped with a filter () configured for extracting from said power supply signal () a signal () representing the modulating wave (), the processing unit () being configured for associating with the pulses detected the values of a phase parameter (f) representing the phase of the modulating wave () at the pulse detection instants.
