  • Sensing, in a first protective relay associated with a first point on the power system, a power system event;

    Recording, in the first protective relay, a time tag of the power system event and a first set of one or more cycles of power system data relating to the event;

    Initiating the communication of a data message to other protective relays over a peer-to-peer communications network, the data message including the time tag;

    Determining, in each of the other protective relays, a set of power system data corresponding to the first set, based on the time tag in the data message; and
