Current and voltage patterns, appliance energy management, granular energy monitoring, nonintrusive load monitor (NILM)
Monitoring of multiple electric loads from a single point
Conventional load monitoring schemes require separate metering equipment or connections for every load of interest.
The technology is a transient event detector implemented with custom analog hardware and a digital signal processing (DSP) computer. The event detector searches for a time pattern of segments or sections of a complete transient which exhibit significant variation (v-section) in different appliances turned-on, in order to identify shapes, amplitude and duration of transients for various appliances’ loads identification.
