4–12 350 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL
A3 RECORDS CHAPTER 4: ACTUAL VALUES
A3 Records
The 350 has an event recorder which runs continuously. All event records are stored in
memory such that information is maintained for up to 3 days even after losing relay
control power. The events are displayed from newest to oldest event. Each event has a
header message containing a summary of the event that occurred, and is assigned an
event number equal to the number of events that have occurred since the recorder was
cleared. The event number is incremented for each new event.
Event records
The Event Recorder runs continuously, capturing and storing the last 256 events. All events
are stored in non-volatile memory where the information is maintained, even in the case
where relay control power is lost.
Shown below is an example of an event record caused by a Breaker Open operation, and
the recorded information at the time of this record.
