Operand description
SvEng data item in associated control block is on
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
Same set of operands as shown for PMU 1
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 for SELECTOR 1
Setting group 1 is active
Setting group 2 is active
Setting group 3 is active
Setting group 4 is active
Setting group 5 is active
Setting group 6 is active
Source 1 disturbance detector has operated
Source 2 disturbance detector has operated
Source 3 disturbance detector has operated
Source 4 disturbance detector has operated
Source 1 VT fuse failure detector has operated
Source 1 VT fuse failure detector has dropped out
Source 1 has lost voltage signals (V2 below 10% and V1 below 5% of nominal)
Source 1 has triggered a VT fuse failure alarm
Source 1 VT neutral wire open detected. When the VT is connected in Delta,
do not enable this function because there is no neutral wire for Delta
connected VT.
Same set of operands as shown for SRC1 VT FF
