Systems and methods for characterizing a device that operated to clear a fault in a power line, such as a power distribution system feeder, are disclosed. Characterizing the device may include receiving measured data corresponding to a current measured along the feeder proximate a substation bus, determining from the measured data that a fault has occurred in at least one phase and has been cleared, subtracting reference data from the measured data to estimate residual fault data, and estimating from the residual fault data a characteristic of the device that operated to clear the fault. The systems may include an Intelligent Electronic Device (IED) and a processor linked to the IED. |
