The present disclosure pertains to systems and methods for obtaining and processing high-frequency electric power system measurements for control and monitoring of an electric power system. High-frequency measurements may be used to detect traveling waves and/or to detect faults in the electric power system. In various embodiments, a processing device may receive high-frequency electric power system measurements from each of a local location and a remote location and may process the high-frequency electric power system measurements to identify and locate a fault. The occurrence of and location of a fault and may be used to implement protective actions to remediate identified faults.
