Abstract
A utility meter includes a meter housing in which are supported at least one current coil, a temperature sensor, and a processing circuit. The current coil can be coupled to receive heat energy from within or on the meter socket. The temperature sensor generates a sensor signal based on a temperature within the meter housing. The processing circuit is operably coupled to the temperature sensor and the at least one current coil. The processing circuit obtains the sensor signal and generates temperature information therefrom, and also generates measurements of current through the current coil. The processing circuit generates an adjustment based at least on the square of the measured current, and determines whether an abnormal condition exists based on the temperature information, the adjustment, and a threshold. The processing circuit can generate an output signal to a display or communication circuit responsive to determining that the abnormal condition exists.
