Abstract :
This paper presents the application of a dyadic wavelet to investigate transformer inrush current. Inrush currents are simulated using the Electromagnetic Transient Program (EMTP). Different values of remnant flux and point of voltage switch-on are chosen to produce various inrush current waveforms. The dyadic wavelet is applied to analyze the signature of the simulated inrush waveforms. Preliminary results are presented
