Abstract
A system, method and device for detecting power grid equipment degradation is provided. In one embodiment, a method of using a device comprises measuring a first voltage of a first energized conductor of a power line connected to the output of a distribution transformer supplying power to one or more customer premises, processing data of the measured voltage to detect a trigger condition wherein the trigger condition comprises, at least in part, a change in the first voltage that extends for at least a first duration, and transmitting a notification of a detection of a trigger condition to a remote computer. The method may further include measuring a second voltage of a second energized conductor and wherein the trigger condition comprises detecting concurrently for at least the first duration a difference between the first voltage and the second voltage that exceeds a first threshold, and a sum of the first voltage and the second voltage that is within a predetermined voltage range. In addition, processing data of the measured voltage to detect a trigger condition may include comprise processing the data to determine whether the first voltage changes beyond a first threshold within a first predetermined maximum time period and remains beyond the first threshold for at least a second duration.
