Power signals corresponding to home electrical appliances randomly switched on and off

The file entitled "Powers_features.txt" contains the power signals obtained from voltage and currents measurements sampled at 5 kHz. 

The lines contains the power samples (computed every M=Fs/F0 samples such as M=5000/50 where F0 is the utility frequency) and the columns are the different active and reactive power features sorted in this order:

{'P','P_{1}','P_{2}','P_{3}','P_{4}','P_{5}','P_{6}','P_{7}','P_{8}','P_{9}','P_{10}','P_{11}','P_{12}','P_{13}','P_{14}','P_{15}','P_{H}', 'Q','Q_{1}','Q_{2}','Q_{3}','Q_{4}','Q_{5}','Q_{6}','Q_{7}','Q_{8}','Q_{9}','Q_{10}','Q_{11}','Q_{12}','Q_{13}','Q_{14}','Q_{15}','Q_{H}'}
