6–16 345 TRANSFORMER PROTECTION SYSTEM – INSTRUCTION MANUAL
S1 RELAY SETUP CHAPTER 6: SETPOINTS
TRIGGER ON PKP
Range: Off, On
Default: Off
Selection of “Yes” setting enables triggering for the recorder upon Pickup condition
detected from any protection or control element.
TRIGGER ON DPO
Range: Off, On
Default: Off
Selection of “Yes” setting enables triggering for the recorder upon a Dropout condition
detected from any protection or control element.
TRIGGER ON TRIP
Range: Off, On
Default: Off
Selection of “Yes” setting enables triggering for the recorder upon Trip condition
detected from any protection or control element.
TRIGGER ON ALARM
Range: Off, On
Default: Off
Selection of “Yes” setting enables triggering for the recorder upon Alarm condition
detected from any protection or control element.
TRIGGER ON INPUT 1 to 3
Range: Off, Contact Input 1 to 10, Virtual Input 1 to 32, Remote Input 1 to 32, Logic
Element 1 to 16
Default: Off
Selection of input or logic element from the settings range enables triggering input for
the recorder. A record will be triggered if the status of the selected input changes to “On”.
Fault report
The 345 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
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.
