SYSTEMS, METHODS, AND DEVICES FOR MONITORING A CAPACITOR BANK

摘要

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.
