This paper presents a wavelet based technique for detection and classification of abnormal conditions that occur on power distribution lines. The transients associated with these conditions contain a large spectrum of frequencies, which are analyzed using wavelet transform approach. The proposed technique depends on a sensitive fault detection parameter (denoted SFD) calculated from wavelet multi-resolution...
Harmonics in voltages and currents comes from the daily equipments used in homes, industrial facility and offices. Any devices with non-linear characteristics may be injecting back harmful harmonic currents and voltages into the electrical system. Power quality has become a factor in our life and harmonics may affect the whole electrical environment and it can further degrade the power quality. In...
