contents Online partial discharges localization system Primo Alberto Calva Chavarria Diana Torres Peñaloza Carlos Ramírez Pacheco Ingeniería FFT PD 's radiometric discone antenna In this paper the design and construction of an online non-invasive non-invasive partial discharges (PD) localization system is presented; it is integrated by four equal discone antennas with a wideband of 30 MHz to 1.2 GHz and a central frequency of 615 MHz connected to a four-channel high-resolution digital oscilloscope. The obtained electromagnetic signals are processed in a personal computer using Wavelet Transform and Fast Fourier Transform (FFT) to reduce electromagnetic noise and identify the source of the PD respectively. Additionally, a spherical algorithm for spatial localization in R3 is used. High-voltage laboratory and in situ measurements are reported. 2013 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43027041007 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.66
