Systems, Methods, and Apparatus for Recording Network Events Associated with a Power Generation or Delivery System
First Claim
1. A network recorder for use in a power generation and/or delivery and/or protection system including one or more intelligent electronic devices wherein each device is coupled to a communications network comprising:
- i) a network port coupled to the communications network and adapted to send and receive packets;
ii) a storage device coupled to the network port for storing the packets; and
iii) a processor coupled to the network port and the storage device, wherein the processor generates an event report on recognition of a trigger, the event report including at least one of the stored packets.

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.
