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

The present disclosure pertains to novel systems and methods that incorporate advanced inference algorithms can be developed to detect floating neutrals using phasor measurements. In one aspect, the present disclosure relates to the use of phasor measurements to detect and localize floating neutrals in a distributed power network.

Floating neutral detection and localization system and methods

Systems and methods for synchronized phasor measurement in a power distribution network are described. In an aspect, the systems and methods quantify the phase angle between voltages or currents at any two points in the distribution network. In another aspect, the systems and methods establish a common time reference between points on a power distribution network by transmitting a synchronization pulse throughout the distribution network. In an additional aspect, the systems and methods extract phasors from a power line waveform by utilizing a phase-locked loop (PLL) and regression of the zero-crossings of the PLL output waveform.
