An Evaluation of Smart Electricity Meters in Noisy Electromagnetic Environments

Ashraf Gaber Hassan, Sohair F. Mahmoud, Hadia El Hennawy

Due to increasing of electronics and digital circuits in all sides of daily life, the electromagnetic pollution is increasing daily. The performance of electronic and electrical equipment is much influenced by this electromagnetic pollution. Now day most of energy meters are still electromechanical. But due to the advantages of smart meters, the conventional meters are being replaced by them. As part of a smart grid, smart meters will be everywhere, and not always in the most ideal operating conditions (inside transformer rooms or near to mobile phone base stations). So these EM noises might affect the performance of meters. EMI/EMC evaluation has thus become necessary to ensure that these meters work satisfactorily in the present day environment. Investigations of the performance of smart meter under radiated electromagnetic disturbances will be studied in this paper. Their performance characteristics with respect to the ones measured in absence of electromagnetic field will be compared.
