Patent number: 9400305Abstract: 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.Type: GrantFiled: May 28, 2010Date of Patent: July 26, 2016Assignee: TECHIMP HQ S.R.L.Inventors: Fabiano Bettio, Gian Carlo Montanari

Patent number: 8990035Abstract: An instrument (1) and a method for detecting partial electric discharges involve acquiring a discharge signal (10), for example picked up by a direct-measuring impedance device (7) through a broadband HF acquisition channel (18), and acquiring the discharge signal (10) in a narrowband LF acquisition channel (180) complying with regulations, using on the LF acquisition channel (180) a trigger controlled in slave mode by a trigger of the broadband HF acquisition channel (18); they also involve acquiring another discharge signal (32) picked up by an indirect-measuring impedance device (8) through a second narrowband LF acquisition channel (180A) and comparing digital signals (34, 34A) generated in the first and second LF acquisition channels (180, 180A), in order to generate a balanced digital signal (36) without components representative of common mode electrical signals present in the measuring circuit.Type: GrantFiled: March 4, 2011Date of Patent: March 24, 2015Assignee: Techimp HQ S.R.L.Inventors: Stefano Serra, Gian Carlo Montanari, Fabiano Bettio
