Abstract:Static, or electronic, energy meters are replacing old fashioned electromechanical energy meters based on the Ferraris principle. Renewable energy and the large variations in energy supply and demand as function of time resulted in a need for smart energy meters. A smart energy meter has communication capabilities added to the standard static energy meter. Previous research showed that static meters can give faulty energy readings. Many cases have been reported where static meters give very high energy readings, which cannot be explained based on the residence situation. It is of great interest to investigate this kind of cases and find the source that causes interference on static meters. For that reason, a control meter is developed which can act as a reference for installed static meters. This control meter is placed next to the static meter and can: measure the energy consumption in a verified and correct manner, readout the static meter, measure the electromagnetic environment, and log the data. Furthermore, it is designed such that it is hardened against the electromagnetic environment. This control meter is now already in use to investigate possible deviations and their causes in static meters.
