Patent number: 10571510Abstract: A partial discharge detecting device includes an electric field sensor including: a first electrode configured to detect by capacitive coupling a partial discharge signal generated by an electrical object and to provide a corresponding first electrical signal, and a second electrode isolated from the first electrode and structured to detect an environmental noise and to provide a corresponding second electrical signal. The detecting device further includes a transmission line structured to propagate an output signal obtained from the electric field sensor toward an external analysis apparatus and an electronic module connected to the first and second electrodes and structured to process the first and second electrical signals and to provide the output signal to the transmission line. The electronic module is structured to decouple the electric field sensor from the transmission line and avoid resonance of the electric field sensor with the transmission line.Type: GrantFiled: May 16, 2014Date of Patent: February 25, 2020Assignee: PRYSMIAN S.p.A.Inventors: Antonio Di Stefano, Roberto Candela, Giuseppe Fiscelli

Patent number: 8816700Abstract: A partial discharge detection device for detecting and measuring partial discharges in electric systems or components, which delivers signals having a form much resembling that of the radiated pulse, for improved identification and analysis. The device is of small size, totally insulated and self-powered, and allows measurements to be performed with the highest safety with no need for direct connection, thereby allowing operators to stand at a distance and avoid any system shutdown while making measurements. Furthermore, it can also detect and deliver the sync signal, which is obtained by picking up the supply voltage of the discharge generating components.Type: GrantFiled: June 11, 2009Date of Patent: August 26, 2014Assignee: Prysmian S.p.A.Inventors: Antonio Di Stefano, Roberto Candela, Giuseppe Costantino Giaconia, Giuseppe Fiscelli
