Home Electrical Appliances Recordings for NILM

We introduce a novel dataset containing a total of 61 distinct HEAs. The proposed appliances (e.g. fans, fridges, washers, etc.) are of different kinds, ages, brands and powerlevels. They have been recorded in steady-state conditions in a French 50 Hz electrical grid. The measurement setup consists of an AC current probe (E3N Chauvin Arnoux) with a 10 mV/A sensitivity and a differential voltage probe witha 1/100 attenuation. Voltage and current waveforms were captured by an 8-bit resolution digital oscilloscope (RIGOL DS1104Z) each corresponding to an acquisition of 8 periods of the utility frequency. The sampling rate was set at Fe=250 kHz for some of the recordings and Fe = 50 kHz for the other part. Each HEA is described by 8 periods of the current and voltage steady-state waveforms, resulting consequently in a set of n = 8 * 61 = 488 distinct individuals.
