Sir, why you choose DWT? Isn't it possible to detect fault by only considering the faulty phases current values?
Please explain me...

[@DrJALAGHARI]

Thanks for the comment. By measuring only the values, there may be difficulty in distinguishing between different faults. Therefore, we use signal processing techniques to extract the features such as energy, coefficients etc to distinguish between the faults and normal scenarios.

What is the significance behind taking only maximum of all wavelet coefficients in the program sir

[@DrJALAGHARI]

Thanks for the comment. basically wavelet provides more samples of around 200. but we need one sample value in order to use it for identification and classification.

[@charanchandra3216]

@@DrJALAGHARI Yes sir basically wavelet coefficients of waveform represent current properties how ever during fault current is high so here taking max of wavelet indicates max current.So directly using current magnitude we can determine fault but what is use of wavelet then

[@DrJALAGHARI]

@@charanchandra3216 Thanks for the comment. Yes you are right. detection requires fast speed for reliable operation. wavelet is used to get few important samples in order to distinguish between different types of faults. using direct maximum values have thousands of samples, which will have difficulty to find the threshold setting value.

[@charanchandra3216]

@@DrJALAGHARI yes sir we need faster approach but my doubt is that max wavelet coefficient occur at max current instant and wavelet is replica of current in that program then by seeing mag of current itself we can decide type of fault then what is the use of wavelet.l mean what extra feature is provided by wavelet compared to current waveform

@@charanchandra3216 i think im the real system there are continuous signal in order to distinguish between all type of faults we need samples. Otherwise it may not be possible.
