Abstract: Systems and methods for identifying and managing stress conditions, risk state or aging state associated with capacitors associated with electrical equipment in an electrical power system are disclosed herein. In one aspect, a method for identifying and managing stress conditions, risk state or aging state associated with at least one capacitor includes detecting at least one of motion of and sounds associated with the at least one capacitor, and analyzing at least the detected at least one of motion of and sounds associated with the at least one capacitor to identify possible stress conditions, risk state or aging state associated with the at least one capacitor and associated components. In response to identifying possible stress conditions, risk state or aging state, probable impacts of the possible stress conditions, risk state or aging state on the at least one capacitor and associated components may be determined.

Abstract: Systems, methods, and devices for monitoring one or more capacitor banks are presented herein. One concept of the present disclosure is directed to a method of monitoring at least one capacitor bank having a plurality of steps. The method includes: receiving measurements indicative of voltages and/or currents on electrical lines coupled to the steps of the capacitor bank by corresponding contactors; receiving information indicative of the respective statuses of the contactors; timestamping the measurements and contactor status information; storing the timestamped measurements with corresponding timestamped contactor status information; determining a rate of change of a parameter indicative of or derived from at least the measurements associated with at least one of the steps in the capacitor bank; comparing the determined rate of change with a baseline rate of change to produce a deviation; determining if the deviation satisfies a criterion; and, if so, indicating the deviation satisfied the criterion.
