Journal ArticleDOI
Antenna Parametrization for the Detection of Partial Discharges
Guillermo Robles,Matilde Sanchez-Fernandez,Ricardo Albarracin Sanchez,M. V. Rojas-Moreno,Eva Rajo-Iglesias,Juan Manuel Martínez-Tarifa +5 more
TL;DR: In this paper, four antennas are thoroughly studied by means of their theoretical and experimental behavior when measuring electromagnetic pulses radiated by PD activity and the results are analyzed in detail.
Journal ArticleDOI
Inductive Sensor Performance in Partial Discharges and Noise Separation by Means of Spectral Power Ratios
TL;DR: Two inductive sensors with different frequency responses to pulsed signals, a high frequency current transformer and an inductive loop sensor are analyzed to test their performance in detecting and separating the sources of partial discharges.
Journal ArticleDOI
Location of partial discharges sources by means of blind source separation of UHF signals
TL;DR: In this paper, the blind source separation (BSS) technique is applied to pairs of UHF sensors to extract the information of the difference of the time of arrival of the electromagnetic pulses radiated by a source of PD.
Proceedings ArticleDOI
Antenna selection and frequency response study for UHF detection of partial discharges
Guillermo Robles,Juan Manuel Martínez-Tarifa,M. V. Rojas-Moreno,Ricardo Albarracín,Jorge Alfredo Ardila-Rey +4 more
TL;DR: In this paper, four antennas were tested in order to compare their response to the physical phenomenon of partial discharges, and the results showed that the UHF-based partial discharge detection is more sensitive to many noise sources.
Journal ArticleDOI
Partial discharge pulse shape recognition using an inductive loop sensor
TL;DR: In this article, a simple, inexpensive and high-frequency inductive loop sensor was used to detect and acquire PD pulses, and several measurements were made on some controlled test cell geometries in order to characterize PD pulse shapes for different discharge sources.
