Abstract
Disclosed herein is a power measurement system capable of power of electric devices without performing a quantization process through a separate analog-digital converter for voltage. The power measurement system includes a smart meter measuring a voltage root mean square value input to an electrical device; and a power measurement device measuring power of the electrical equipment using a voltage root mean square value Vrms measured by the smarter meter and a current instantaneous values of power lines connected to the electric device.
Claims7
