description

Abstract A mixed electronic system has been designed to measure the active, apparent and reactive energies delivered to a load in a single-phase AC voltage line. For this purpose a smart sensor (ADE7753 from Analog Devices) was used. A magnetoresistance sensor is used as a current transducer and it is constant current biased by a generalized impedance converter. The magnetoresistance sensor technology provides direct isolation from the mains voltage and ferrite cores are not needed like Hall counterparts. All the measurements provided by the ADE7753 are read through the parallel port of the computer using a LabView application, which will process and present the readings to the user.
