Due to the </em><em>continuous increase of energy and especially electricity tariffs, consumers are looking for </em><em>accurate meters that give the right measurement. However, the use of nonlinear loads leads to </em><em>current and voltage harmonics production which presents the main cause of power losses, </em><em>current and voltage distortion waveforms and measurement errors. In fact, this paper presents a </em><em>comparative study of two types of energy meters which are Electromechanical and Smart Meter </em><em>by giving the architecture and the accuracy of each meter and discussing the error sources </em><em>coming from the meters itself. Moreover, it focuses on the effects of harmonics on the energy </em><em>measurement and put attention on the importance of using an error function to estimate the error </em><em>measurement value of the energy meter. Simulation results present the behavior of the two types </em><em>of meters under harmonics, give an error function using System Identification Toolbox which is a </em><em>linear ARX model and finally, prove that electronic meter gives less error and presents better </em><em>performance under distorted current and voltage waveforms than the electromechanical meter.</em></p> ER -
