Title:
Current/Voltage Measurement Scheme Using a Flexible Coil/Electrode Power Sensor to Monitor the Power of Two-Wired Household Appliances
Author Name:

Abstract:
ABSTRACT This study develops a non-intrusive power sensor for the electricity monitoring of two-wire household appliances. The information provided by a power sensor supports home energy management systems and encourages energy-saving behavior for each household member, resulting in an increasingly efficient energy usage. The flexible non-intrusive power sensor is fabricated with a current and a voltage sensing parts on a 100 μm thick flexible polyethylene terephthalate substrate. The combination of a 30-turn coil design with two sensing electrodes in an area of 0.25×1 cm2 exhibits power sensor sensitivities of 20.6 μV/A and 63.9 μV/V for detecting 60 Hz electric current and voltage, respectively. For the practical application, the method of calibration is also proposed in the paper. Keywords: Current measurement, Voltage measurement, Non-intrusive, Calibration.
