Abstract

An electric utility meter including a three-axis Hall Effect sensor configured to detect the presence of a magnetic field in two or more directions surrounding the electric utility meter. The electric utility meter also includes a controller having an electronic processor. The controller is configured to receive a signal indicative of an abnormal magnetic field proximate the electric utility meter from the three-axis Hall Effect sensor, determine an amount of time for which the abnormal magnetic field has been detected, and log a magnetic field tamper event in an event log when the amount of time for which the abnormal magnetic field has been detected exceeds a threshold.
