Patent number: 11189421Abstract: A current sensing modular system, which allows sensing the phase current and/or the around-fault or zero-sequence current, having to that end at least a first module having at least one phase current sensor embedded therein and a second module having a zero-sequence current sensor embedded therein. The first module is independent of the second module, both modules being installed directly in the connection elements, i.e., in the connection point between at least one bushing and at least one connector of at least one grid cable.Type: GrantFiled: October 26, 2017Date of Patent: November 30, 2021Assignees: ORMAZABAL PROTECTION & AUTOMATION, S.L.U., ORMAZABAL Y CIA., S.L.U.Inventors: Luis Ranedo Torres, Miguel Alvarez Escalona, Jose Luis Sabas Fernandez, Juan Antonio Sanchez Ruiz

Publication number: 20190287718Abstract: The present invention relates to a current sensing modular system, which allows sensing the phase current and/or the ground-fault or zero-sequence current, having to that end at least a first module (7) comprising at least one phase current sensor (5) embedded therein and a second module (8) comprising a zero-sequence current sensor (6) embedded therein. According to the invention the first module (7) is independent of the second module (8), both modules (7, 8) being installed directly in the connection elements, i.e., in the connection point between at least one bushing (2) and at least one connector (4) of at least one grid cable (3).Type: ApplicationFiled: October 26, 2017Publication date: September 19, 2019Applicants: Ormazabal Protection & Automation, S.L.U., Ormazabal Y CIA., S.L.U.Inventors: Luis Ranedo Torres, Miguel Alvarez Escalona, Jose Luis Sabas Fernandez, Juan Antonio Sanchez Ruiz

Publication number: 20190157017Abstract: The present invention relates to a drive system for high-voltage electrical devices, such as a load break switch-disconnector and a grounding disconnector, which can be applied in utility grids, allowing said drive system to motorize the switching of both electrical devices. To that end, the drive system comprises a subassembly which allows selecting the motorized switching operation of the first electrical device or the motorized switching operation of the second electrical device. The motorization of the switching of both electrical devices thereby allows performing said operation remotely.Type: ApplicationFiled: November 20, 2018Publication date: May 23, 2019Inventors: Juan María Casado Cartón, José Luis Sabas Fernandez

Patent number: 10193272Abstract: Enables an electrical connection to be made in an insulated, shielded manner that makes it possible to sense a voltage presence signal, between the cable (3) and the electrical equipment with a female bushing (4) without the need to substitute or modify the high-voltage electrical equipment (2), only adding fastening elements for the adapter (1). Said adapter (1) comprises a body (6) of insulating material, equipped with a first connection end (8) configured to couple in a sealed manner into said at least one female bushing (4) of the high-voltage electrical equipment (2) and with a second connection end (9) configured to couple to the female terminal (5) of the cable (3).Type: GrantFiled: December 1, 2014Date of Patent: January 29, 2019Assignee: ORMAZABAL Y CIA, S.L.U.Inventors: Sergio Sebastián Martín, Luis Ranedo Torres, Joseba Arostegui Legarreta, José Luis Sabas Fernández
