Abstract
A method for recording analog signals and digitally encoded information associated with primary and secondary devices of an electric power system includes: receiving a plurality of analog output signals and a plurality of ON/OFF status signals from the electric power system; receiving a time-synchronization analog signal and/or a time-synchronization data packet from a time synchronization source; maintaining an internal clock synchronized with the synchronization source; sampling and digitizing the plurality of analog output signals; monitoring a status and/or a change of status of the plurality of ON/OFF status signals; receiving digitally encoded information signals as incoming data packets; decoding and analyzing the incoming data packets; analyzing the plurality of analog output signals and digitally encoded information signals using a triggering algorithm; and storing digitized analog output signals and digitally encoded information signals together with corresponding timing information in a record as fault and sequence of events records.
