Part 2: practical assessment and validation Eduardo Gómez Luna Juan Sebastián Cuartas Bermúdez Eduardo Marlés Sáenz Ingeniería frequency response online supervision and control Continuous wavelet transform (CWT) power system transients and transformers This article presents a practical assessment and validation of the new proposed approach based on the continuous wavelet transform (CWT) to obtain the electrical impedance phase from online transient signals for a real transformer. Besides the mathematical procedure presented in a previous paper, an electronic system was also designed and implemented, in order to inject superimposed controlled pulses to the power system (50/60 Hz) wave. The results show improved performance of the wavelet transform compared to that of the Fourier Transform, for transient signal analysis to be applied on a nonintrusive transformer monitoring approach. Particularly, this new approach proves useful in overcoming problems related to signal filtering and signal processing in an online frequency-response analysis of a transformer diagnosis. 2018 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49657889013 https://www.redalyc.org/journal/496/49657889013/ https://www.redalyc.org/journal/496/49657889013/html/ https://www.redalyc.org/journal/496/49657889013/49657889013.epub https://www.redalyc.org/journal/496/49657889013/movil 10.15446/dyna.v85n205.68458 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.205 Vol.85 |
