Abstract
A network recorder adapted for use within power generation, delivery and protection systems and/or process control systems is disclosed. The network recorder itself comprises a network port coupled to a communications network utilized by a monitoring, control, automation, and protection system. A storage device stores packets that are communicated on the communications network in conjunction with other calculated or measured information. The network recorder also includes a processor that generates an event report on reception of a trigger, where a trigger can be any external event, including the operation of a relay contact, or the occurrence of a packet or sequence of packets indicating a protection operation by a power protection device within the power protection system. The generated event report includes packets that were communicated on the communications network temporally coincident with the trigger.
