Figure 13-19. Current Differential Relay SOE Settings
SOE Settings Definitions:
Fault Detectors
Setting this to “Yes” will allow the fault detectors to trigger a SOE recording. A change of state
(becoming active or inactive) in any of the fault detectors for any phase or ground will initiate an SOE
recording.
External Dual Breaker Fault
Setting this to “Yes” will allow detection of an external dual breaker fault to initiate an SOE recording.
See section 13.5.1.1.7
Major Alarm
Setting this to “Yes” will allow the major alarm to trigger a SOE recording. A change of state
(becoming active or inactive) in the major alarm will initiate an SOE recording. See section 13.5.2.4
for further information.
Minor Alarm
Setting this to “Yes” will allow the minor alarm to trigger a SOE recording. A change of state
(becoming active or inactive) in the minor alarm will initiate an SOE recording. See section 13.5.2.5
for further information.
Curr Diff Alarm
Setting this to “Yes” will allow the current differential alarm to trigger a SOE recording. A change of
state (becoming active or inactive) in the current differential alarm will initiate an SOE recording. See
section 13.5.1.2.11 for further information.
Comms Enable
Setting this to “Yes” will allow a change in state in the comms to trigger an SOE record (becoming
inactive).
Ping-Pong Alarm
Setting this to “Yes” will allow the ping-pong alarm to trigger a SOE recording. A change of state
(becoming active or inactive) in the ping-pong alarm will initiate an SOE recording. See section
13.5.2.6.4 for further information.
Address Failure
The relay verifies communications with the proper remote relay using an addressing scheme (see
section 13.5.2.6.1). Setting this to “Yes” will allow an address failure (or recovery from an address
failure) to trigger an SOE recording.
Comms Failure
Setting this to “Yes” will allow the communications failure flag to trigger a SOE recording. A change
of state (becoming active or inactive) in the communications failure flag will initiate an SOE
recording. See section 13.5.2.6.3 for further information.
Remote # 1 Fault Detector
Setting this to “Yes” will allow a change in the status of the remote # 1 relays fault detector, triggering
an SOE recording.
