Design and Characterization of a Magnetic Loop Antenna for Partial Discharge Measurements in Gas Insulated Substations

Mier Escurra, Christian; Rodrigo Mor, Armando; Vaessen, Peter (Institute of Electrical and Electronics Engineers, 2021-09-01)

[EN] A recent investigation explored a new measuring concept used in partial discharges (PD) measurements in gas insulated substations (GIS), consisting of a magnetic loop antenna. The sensor¿s frequency response was ...
Detección de descargas parciales en el sistema aislante de los motores eléctricos como técnica de mantenimiento predictivo

Ferrer Redondo, Ana Belén (Universitat Politècnica de València, 2021-10-08)

[ES] En el presente trabajo se recoge de manera descriptiva un estudio sobre las descargas parciales en el sistema de aislamiento de los motores eléctricos como método para controlar el estado en el que se encuentra el ...
High Performance Broadband Capacitive Coupler for Partial Discharge Cable Tests

Rodrigo Mor, Armando; Llovera Segovia, Pedro; Fuster Roig, Vicente Luis; Quijano Lopez, Alfredo (Institute of Electrical and Electronics Engineers (IEEE), 2013-04)

[EN] Partial discharge (PD) cable field tests require the use of high frequency sensors coupled to the cable for PD apparent charge evaluation. PD sensors can be coupled to the cable by magnetic field, like high frequency ...
Influence of High Frequency Current Transformers Bandwidth on Charge Evaluation in Partial Discharge Measurements

Rodrigo Mor, Armando; Llovera Segovia, Pedro; Fuster Roig, Vicente Luis; Quijano Lopez, Alfredo (Institute of Electrical and Electronics Engineers (IEEE), 2011-10)

[EN] High frequency current transformers (HFCT) are now widely used for partial discharges detection and measurement, specially for partial discharge location and source identification. However, many difficulties arise due ...
Investigation of Factors Affecting Partial Discharges on Epoxy Resin: Simulation, Experiments and Reference on Electrical Machines

Verginadis, Dimosthenis; Karlis, Athanassios; Danikas, Michael; Antonino-Daviu, J. (MDPI AG, 2021-10)

[EN] In Power Systems, SG are mostly used for generating electricity. Their insulation system, of which epoxy resin is a core component, plays a significant role reliable operation. Epoxy resin has high mechanical strength, ...
Localization techniques of partial discharges at cable ends in off-line single-sided partial discharge cable measurements

Rodrigo Mor, Armando; Morshuis, P. H. F.; Llovera Segovia, Pedro; Fuster Roig, Vicente Luis; Quijano Lopez, Alfredo (Institute of Electrical and Electronics Engineers (IEEE), 2016-03)

Partial discharge (PD) field tests are widely used for cable assessment or cable commissioning. Usually, these tests are carried out by means of off-line tests where PD pulses are measured with capacitively coupled PD ...
Magnetic and electric antennas calibration for partial discharge charge estimation in gas-insulated substations

Mier, Christian; Rodrigo Mor, Armando; Castro, Luis; Vaessen, Peter (Elsevier, 2022-10)

[EN] There are no accepted procedures that quantify the apparent charge of partial discharge (PD) in gas-insulated substations (GIS). This paper proposes a calibration method for PD charge estimation using unconventional ...
Magnetic and electric antennas synergy for partial discharge measurements in gas-insulated substations: Power flow and reflection suppression

Mier, Christian; Rodrigo Mor, Armando; Vaessen, Peter; Lathouwers, André (Elsevier, 2023-01)

[EN] One of the main difficulties in measuring partial discharges (PD) in gas-insulated substations (GIS) is the overlapping of pulses at the sensor's location, which distorts the pulse resolution and the charge estimation. ...
