Because the current meter does not have the function of detecting electromagnetic fields, there is nothing to do when the meter is disturbed by the high-power electromagnetic field. In order to avoid this kind of electricity stealing behavior, this paper studies how to quickly detect the electromagnetic interference outside the meter based on the characteristics of the meter itself, and timely implement the alarm to prevent electricity theft. In this paper, a feasible and effective electromagnetic field detection technology scheme is proposed, which can detect the electromagnetic field strength around the electric energy meter in real time. When the electromagnetic field intensity reaches the threshold value that affects the metering function of the electric function meter, the electromagnetic field detection module will perform alarm behavior.
