Hi, I wish to use wavelet transform in matlab to find fault location in transmission line. I have simulated a three phase fault in matlab and load the signal into wavelet toolbox after modal transformation.
My problem now is that in wavelet toolbox, after I have chosen a mother wavelet and details, how should I obtain the time details of the fault? Is it just choose 2 first peaks from the waveform and calculate the time in between them? I need the time details to input into the formula so that I can get fault location. Please help me. Thank you.

Perhaps you should use findpeaks() to help you out. Just a thought.
