OPERAND DESCRIPTION
Overcurrent trigger of phasor measurement unit 1 has operated
Abnormal frequency trigger of phasor measurement unit 1 has operated
Overpower trigger of phasor measurement unit 1 has operated
Rate of change of frequency trigger of phasor measurement unit 1 has
operated
Abnormal voltage trigger of phasor measurement unit 1 has operated
Phasor measurement unit 1 triggered; no events or targets are generated by
this operand
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
Indicates the one-shot operation is pending; that is, the present time is before
the scheduled one-shot time
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
