| description |
Partial Discharges (PD) are one of the possible causes for unexpected faults in power systems equipment, so that its measure is an essential tool for high-voltage electrical equipment maintenance. In order to characterize the PD activity, some statistic magnitudes are necessary. For this reason, the acquisition and processing of PD is very important when making critical decisions regarding disconnection or repairing assets in power systems. On the other hand, the measurement environments often present multiple sources of electrical noise, thus the proper interpretation of PD patterns is a challenge in the identification of sources of different nature. In this paper, the development of a PD monitoring system capable of displaying in real time the classic PD parameters, the PD waveform, its frequency spectrum and calculating statistical parameters of the acquisition, are presented. On the whole, a new method of identifying sources of PD and electrical noise, developed by the authors, which is based on measuring the relative spectral power of PD pulses, is shown. This method has proven effective in characterizing PD and electrical noise; a series of experiments conducted in several test objects are presented in order to validate the performance of the proposed system |

Con el fin de caracterizar la actividad de PD, algunas magnitudes estadísticas son necesarias. Por esta razón, la adquisición y procesamiento de PD es muy importante en el momento de tomar decisiones críticas en relación con la desconexión o reparación de los sistemas de potencia. Por otro lado, los entornos de medida suelen tener presentes múltiples focos de ruido eléctrico, por lo que la interpretación adecuada de patrones de PD es un reto al que se añade la identificación de fuentes de diferente naturaleza. En este artículo se presenta el desarrollo de un sistema de monitorización de descargas parciales, capaz de visualizar en tiempo real los parámetros clásicos de descargas parciales, la forma de onda de un pulso de PD, su espectro de frecuencia y calcular los parámetros estadísticos de la adquisición. Conjuntamente se presenta un nuevo método de identificación de fuentes de PD y ruido eléctrico que han desarrollado los autores, el cual se basa en la medida de la potencia espectral relativa de los pulsos de PD. Éste método ha probado ser eficiente en la caracterización de PD y ruido eléctrico, Una serie de experimentos realizados en varios objetos de ensayo son presentados, con el fin de validar el comportamiento del sistema propuesto.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ingenieríahttps://revistas.unal.edu.co/index.php/ingeinv/article/view/53584Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónArdila Rey, Jorge Alfredo and Albarracín Sánchez, Ricardo and Robles, Guillermo (2015) A new monitoring and characterization system of partial discharges based on the analysis of the spectral power.
