Visualization system for electrical power consumption and its evaluation

Abstract

A visualization system for power consumption has been developed. This system has two power measurement devices: a smart power strip that assesses each attached electric device; and a power sensor on the power distribution board. To verify the effectiveness of this system, an evaluation system has also been developed. Results indicate that the relative deviation of the visualization system is around 1% and that its uncertainties are less than 0.4% at 500 W/50 Hz.
