Abstract
An electric utility meter including a Hall Effect sensor configured to sense a magnetic field proximate the electric utility meter. The electric utility meter also includes a controller having an electronic processor, the controller configured to receive a signal indicative of a magnitude of the magnetic field proximate the electric utility meter from the sensor, determine whether the magnitude of the magnetic field exceeds a first magnitude threshold and whether a threshold flag has been set, set the threshold flag when the threshold flag has not been set and the magnitude exceeds the first magnitude threshold, determine an amount of time for which the magnitude has exceeded the first magnitude threshold when the threshold flag has been set, and generate an alert indicative of a magnetic tamper event when the amount of time exceeds a time threshold.
