Abstract
An instrument for detecting partial electric discharges includes: an input stage set up to receive a discharge signal representative of one or more partial discharge pulses and a sync signal representative of an alternating voltage applied to the electric apparatus; a data processing stage for receiving the discharge signal and the sync signal, and extracting substantially in real time for each pulse detected the value of an amplitude parameter, correlated with a pulse amplitude, and the value of a phase parameter, representative of the phase of the voltage applied to the electric apparatus concurrently with the pulse, and transferring to output a processed digital signal including the values extracted. The processing stage includes a filtering module set up to disable substantially in real time the transfer to output of the values of the parameters extracted for one or more pulses.
