Abstract
Method for SEL mitigation involves determining one or more base sets of signature vector components for each of a plurality of signal loading conditions experienced by a protected device in an operating state, each set of base signature vector components together comprising a base signature vector. The method further involves monitoring signature vector components for the protected device to determine a detected signature vector which is comprised of a set of detected signature vector components. The detected signature vector is compared to a dynamically selected base signature vector which is associated with the device state and signal loading condition which are currently active to differentiate between the occurrence of standard current surges associated with normal operation of the protected device and a non-standard current surge.
