Indicates the one-shot operation has been executed, and the present time is
at least 30 seconds past the scheduled one-shot time
Indicates the one-shot operation and remains asserted for 30 seconds
afterwards

The power swing element detected a disturbance other than power swing
An unstable power swing has been detected (incoming locus)
An unstable power swing has been detected (outgoing locus)
Asserted when power swing is detected and de-asserted when a fault during
power swing occurs
