OPERAND DESCRIPTION
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 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 power swing is detected and de-asserted when a fault during
power swing occurs
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
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 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 VT neutral wire open detected.When the VT is connected in Delta,
this function should not be enabled because there is no neutral wire for Delta
connected VT.
Same set of operands as shown for SRC1 VT FUSE FAIL
Disconnect switch 1 open command initiated
Disconnect switch 1 close command initiated
Disconnect switch 1 is closed
Disconnect switch 1 is open
Disconnect switch 1 has discrepancy
Disconnect switch 1 trouble alarm
Disconnect switch 1 phase A is closed
Disconnect switch 1 phase A is open
Disconnect switch 1 phase A bad status is detected (discrepancy between
the 89/a and 89/b contacts)
Disconnect switch 1 phase A intermediate status is detected (transition from
one position to another)
Disconnect switch 1 phase B is closed
Disconnect switch 1 phase B is open
Disconnect switch 1 phase B bad status is detected (discrepancy between
the 89/a and 89/b contacts)
Disconnect switch 1 phase B intermediate status is detected (transition from
one position to another)
Disconnect switch 1 phase C is closed
Disconnect switch 1 phase C is open
Disconnect switch 1 phase C bad status is detected (discrepancy between
the 89/a and 89/b contacts)
Disconnect switch 1 phase C intermediate status is detected (transition from
one position to another)
Disconnect switch 1 bad status is detected on any pole
Same set of operands as shown for SWITCH 1
