Patent number: 9933474Abstract: A partial discharge detection apparatus, includes: a support structure and a first antenna configured to receive electromagnetic signals at least partially associated with partial discharges of an electric object and generate a first electrical signal, the first antenna having a first receiving effective area for first receiving directions and a second antenna configured to receive electromagnetic noise signals and generate a second electrical signal, the first and second antennas being arranged to cause the second antenna to have a second receiving effective area for the first receiving directions smaller than the first receiving effective area. The apparatus further includes a first processing module configured to generate from the first and second electrical signals a difference electrical signal representing a difference between the first electrical signal and the second electrical signal.Type: GrantFiled: June 14, 2012Date of Patent: April 3, 2018Assignee: PRYSMIAN S.P.A.Inventors: Roberto Candela, Antonio Di Stefano, Giuseppe Fiscelli, Giuseppe Costantino Giaconia

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
