Abstract
Disclosed herein are systems and methods for leveraging the inherent redundancy of electrical measurement inputs available to microprocessor based intelligent electronic devices (lEDs). Specifically an IED may receive a plurality of electrical measurements associated with an electric power delivery system such as measurements associated with a generator. A first protection module may be configured to detect a first type of electrical disturbance using a first subset of the plurality of electrical measurements. A second protection module may be configured to detect a second type of electrical disturbance using a second subset of the plurality of electrical measurements. A first redundant protection module may be configured to verify the detection of the first type of electrical disturbance using at least a portion of the second subset of the plurality of electrical measurements.
