Fault Report - GE 339 Instruction Manual

S1 RELAY SETUP

Fault report

6–18
The 339 relay has a Fault Report which captures measured analog signals at the time of
the trip. The Fault Report stores only the last recorded values in relay's non-volatile
memory. The Fault Report has two configurable setpoints, "FAULT TRIGGER" and "DELAY
OTHER TRIGGERS". The high state of the selected Fault Trigger operand will trigger the Fault
Report. The default setting is ANY TRIP. The time delay setting is provided for selection of
time to override any subsequent triggers following the first trigger and prevent losing
information from the record. When this time delay elapses, the fault record can be
updated if new trip exists. The recorded values from the Fault Report can be seen in:
ACTUAL VALUES > A3 RECORDS > FAULT REPORT
The Fault Report header includes the following information:
• Relay model
• Device name
• Firmware revision
• Date and time of trigger
• Name of the trip trigger
• Active setting group at the time of trigger
• All measured analog signals - currents, voltages, RTDs (one cycle after the fault trigger)
The Fault Report runs continuously, capturing and storing the last trip in non-volatile
memory, where the information is maintained even if relay control power is lost. This
record is updated when the fault record delay has elapsed and a new trips occur.
The following path is available using the keypad. For instructions on how to use the
keypad, please refer to Chapter 3 - Working with the Keypad.
PATH:
SETPOINTS > S1 RELAY SETUP > FAULT REPORT
FAULT RECORD TRIGGER
Range: Off, Any Trip, Contact Input 1 to 10, Virtual Input 1 to 32, Remote Input 1 to 32,
Logic Element 1 to 16
Default: Any Trip
This setting selects an operand for triggering the report. The report is triggered at the
rising edge of the selected trigger operand. To avoid inaccuracies during the fault
transient period, data from one cycle after the trigger is collected.
FAULT RECORD DELAY
Range: 0.00 to 600.00 s in steps of 0.01 s
Default: 0.00 s
This setting specifies the time delay after the first trip trigger for the Fault Report, during
which the record is not updated with any subsequent trip triggers.
