Positive-sequence impedance in outer characteristic
Positive-sequence impedance in middle characteristic
Positive-sequence impedance in inner characteristic
Power swing blocking element operated
Power swing timer 1 picked up
Power swing timer 2 picked up
Power swing timer 3 picked up
Power swing timer 4 picked up
Out-of-step tripping operated
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 a fault occurs after the power swing blocking condition has
been established
Selector switch 1 is in Position Y (mutually exclusive operands)
First bit of the 3-bit word encoding position of selector 1
Second bit of the 3-bit word encoding position of selector 1
Third bit of the 3-bit word encoding position of selector 1
Position of selector 1 has been pre-selected with the stepping up control
input but not acknowledged
Position of selector 1 has been pre-selected with the 3-bit control input but
not acknowledged
Position of selector 1 has been pre-selected but not acknowledged
Position of selector switch 1 is undetermined or restored from memory when
the relay powers up and synchronizes to the three-bit input
Same set of operands as shown above for SELECTOR 1
