FLISR is re-triggering on non three-phase trips when another phase has already locked out.
It is expected that if B and C phase lock out and FLISR fails to solve and then A phase locks out, FLISR should not attempt to solve.
How to Repeat
- Set FLISR_SINGLE_PHASE_MODE "Rule Value 2" to "1"
- Set FLISR_VOLT_LOSS_THRESHOLDS "Rule Value 1" to "disabled"
- Restart services
- Set SCADA measurements to OPEN and Indicate a fault (FI) on a single-phase of a breaker.
- Wait 5 seconds and set the Phase Lockout (PL) on the same phase of step 1. for that device.
- Wait 75 seconds so FLISR can run and finish the work.
- Set SCADA measurements to OPEN and Indicate a fault (FI) on a a different single-phase of the same breaker.
- Wait 5 seconds and set the Phase Lockout (PL) on the same phase of step 4. for that device.
- Observe NO duplicate messages on FLISR event shown on Work Agenda.
