Obtaining the electrical impedance phase using Wavelet transform and Fourier transform from transient signals. Part 2: practical assessment and validation

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...

A parte del procedimiento matemático presentado en la parte 1, también se diseñó e implementó un sistema electrónico para inyectar pulsos controlados en la onda del sistema de potencia (50/60 Hz). Los resultados muestran un mejor rendimiento de la Transformada Wavelet en comparación con la transformada de Fourier, para el análisis de señales transitorias para ser aplicado en un enfoque de monitoreo de transformadores no intrusivo. En particular, este nuevo enfoque permite superar algunos problemas de filtrado y procesamiento de señales en el análisis de respuesta en frecuencia de un transformador en servicio.application/pdfspaUniversidad Nacional de Colombia - Sede Medellín - Facultad de Minashttps://revistas.unal.edu.co/index.php/dyna/article/view/68458Universidad Nacional de Colombia Revistas electrónicas UN DynaDynaGómez-Luna, Eduardo and Cuartas-Bermúdez, Juan Sebastián and Marlés-Sáenz, Eduardo (2018) Obtaining the electrical impedance phase using Wavelet transform and Fourier transform from transient signals.
