Name/states/source Status/events/restart/qualifiers
State: Set when an auto-close event has been generated by the Fusesaver.
Cleared by Fusesaver entering the open state or operator trip event, protection
trip event, three-phase lockout event, or backfeed block trip event.
Events: Set event generated when auto-close event has been generated by the
Fusesaver. Cleared event generated when state is cleared as above. Note the
ongoing event is significant, the cleared event should be discarded by the
SCADA system.
On restart: Volatile - state clear on restart.
Data qualifiers: Override, online, communications lost.
State: Set when an operator close event has been generated by the Fusesaver.
Cleared by Fusesaver entering the open state or operator trip event, protection
trip event, three-phase lockout event, or backfeed block trip event.
Events: Set event generated when operator-close event has been generated by
the Fusesaver. Cleared event generated when state is cleared as above. Note the
ongoing event is significant, the cleared event should be discarded by the
SCADA system.
On restart: Volatile - state clear on restart.
Data qualifiers: Override, online, communications lost.
State: Set when Fusesaver VI life is worn out. For a particular Fusesaver, this can
only happen once and will never be reset. When the Fusesaver is replaced, the
bit will be cleared. This status data comes from the Fusesaver live-data stream.
Events: Ongoing event generated from change of state above.
On restart: Volatile - state clear on restart.
Data qualifiers: Override, online, restart, communications lost.
State: Set when Fusesaver has failed to trip or close properly (i.e., a mechanism
fault). Cleared when Fusesaver does trip or close properly. This status data
comes from the Fusesaver live-data stream.
Events: Set event generated by Fusesaver failure to operate event. Cleared
event generated by Fusesaver actuator ok event. These events come from the
Fusesaver event record.
On restart: Volatile - state clear on restart.
Data qualifiers: Override, online, restart, communications lost.
State: Set when a surge-detected event has been registered by the Fusesaver.
Cleared by protection flag reset timer or by operator control.
Events: Set event generated when a surge-detected event has been generated
by the Fusesaver. Cleared event generated when state is cleared as above. Note
that only the ongoing event is significant, the cleared event should be discarded
by the SCADA system.
On restart: Volatile - state clear on restart.
Data qualifiers: Override, online, communications lost.
State: This is a dummy point controlled by the RCU dummy control (C_PID 6)
and is used for test purposes. The point is set and cleared by the RCU dummy
control. No physical control takes place.
Events: Events generated by change of state above.
On restart: Clear on restart.
Data qualifiers: Override.
