A prototype Design for Three Phase Smart Energy Meter

This paper presents design and construction of a three-phase smart energy meter. The meter is designed to overcome the defects of mechanical meters such as moving parts. The smart energy meter has several advantages over the mechanical meter including the automatic data collection, avoiding the errors occur due to manual readings, real-time pricing and provides a more reliable system due to the ability of an immediate fault detection. The designed energy meter computes the power consumption using a microcontroller (Arduino Mega) with the help of three AC current sensors and three AC voltage sensors. The power consumption for each phase can be display on a digital programmed screen. The consumer value of the power can be sent to the monitoring station with the remote transmitting feature. The three phase energy meter was implemented in the laboratory with a current of up to 20 amps and a voltage of up to 250 volts. The Calibration of the designed meter has been taken into account to ensure that the consumer is spent the real amount of the energy that he uses.
