This work proposes, develops, and evaluates a fine-grained high-frequency data acquisition (DAQ) solution to accurately detect individual appliances from the aggregate load, even when several appliances are operating simultaneously. As most disaggregation inaccuracies stem from DAQ, we have developed a circuit-level electric appliance radar to simultaneously gather energy data at up to 250 kHz from six circuits. Similarly, a novel event detection algorithm using the Hilbert-Huang transform is proposed to accurately detect low power appliance events from an office.
