Fault Detection using Discrete Wavelet Transform

Line to Ground fault analysis on a Cable connected from Electric Drive to Induction Motor

This is a line to ground fault analysis on a cable connected from an electric drive to a induction motor using Discrete wavelet transform

Procedure to run the code

1) Run the simulation file "a_Simulation.slx" for fault condition or non fault condition by commenting out the fault signal box

2) Run the matlab code "b_Code_Data_Save.m" to save the corresponding data. If fault block is used in simulation, then appropriate codes should be uncommented in the .m file

3) Run the matlab code "b_Code_Wavelet.m" to get the signal decomposition of both fault and pure signal. Make sure that, previous steps are followed to save both fault and pure signal data. Different wavelets can be chosen in the wavdec function

4) Run the matlab code "d_Code_Coeff_Plotting.m" to get plotting of the decomposed coefficients
