An electric utility meter includes a housing, an input configured on the housing that receives input electricity from an electricity source, and a controller having an electronic processor and a memory. The electronic processor is configured to measure a first characteristic and a second characteristic of the input electricity, determine a fault parameter value, calculate a confidence score corresponding to the fault parameter value, compare the confidence score to a threshold value, and determine that a fault is occurring based on the confidence score exceeding the threshold value.

Systems and methods for estimating neutral impedance and detecting faulted neutral connection in an electrical meter

In some embodiments a method includes receiving, from a sensor device, a signal indicative of a voltage associated with a current passing over a line that is disposed through the sensor device. The method includes receiving, from the sensor device, a signal indicative of (1) a calibrated sensitivity of the sensor device, (2) a calibrated temperature of the sensor device, and (3) an ambient temperature that was received from an ambient temperature sensor. The method includes defining an actual sensitivity of the sensor device based on (1) the calibrated sensitivity of the sensor device, (2) the calibrated temperature of the sensor device, and (3) the ambient temperature. The method includes sending a signal indicative of a modified electric current value based on (1) the voltage and (2) the actual sensitivity of the sensor device.
