A faulty meter socket detection system configured to detect faulty sockets as evidenced by series arcs in an input current waveform or an increased temperature of the meter is disclosed. The system includes a metering circuit configured to receive an input current waveform, and a controller including a power monitoring module. The meter may also include a temperature sensor. The power monitoring module is configured detect series arc currents input current waveform data by filtering the input current waveform data to produce filtered data, performing feature recognition on the filtered data, classifying the features of the filtered data, performing temporal processing on the filtered data, (optionally) scaling the temporal processing of the filtered data, and, scoring the input current waveform based on the temporal processing of the filtered data. The temperature sensor may detect an increased temperature of the meter, which may indicate a faulty socket.

Series arc detection firmware

An electrical meter including a housing including a socket interface operable to connect to a facility. The meter further including a sensor configured to sense a characteristic of the electrical meter. The meter further including a controller having an electronic processor and a memory. The electronic processor is configured to receive, from the sensor, a signal indicative of the electrical characteristic, determine, based on the signal, presence of a hot socket, and output an alert based on determining presence of the hot socket.

System and method for detecting arc in an electrical meter

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.

Magnetic field detection and interaction

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.

Flashlights include an elongated housing, a power source, a switch, and LED light source disposed in a forward portion of the housing to project light through an opening on a forward surface of the housing, and a cooling fin structure extending rearwardly from the forward surface to effectively dissipate generated heat.
