Abstract

(Smart) meters which use Rogowski coils are verified to be sensitive for the high frequency signals. This will lead to incorrect records of consumer's energy consumption. Power electronic devices are the possible harmonic sources. In this paper, the output currents of photovoltaic (PV) systems are measured in the range 2-150kHz and the high frequency harmonic currents are regenerated in the laboratory to investigate their influence on the smart energy meters. It is realized that the insufficient dynamic range in the meters could be the possible reason of inaccuracy. After the experiments, it is concluded that the high frequency current can make the output signal of the Rogowski coil beyond the dynamic range of smart meters and sequentially less registered energy
