Operand description
Permissive under-reaching transfer trip has operated
Permissive under-reaching transfer trip asserts transmit bit number 1
Permissive under-reaching transfer trip asserts transmit bit number 2
Permissive under-reaching transfer trip asserts transmit bit number 3
Permissive under-reaching transfer trip asserts transmit bit number 4
Permissive under-reaching transfer trip has operated to trip phase A
Permissive under-reaching transfer trip has operated to trip phase B
Permissive under-reaching transfer trip has operated to trip phase C
Permissive under-reaching transfer trip has operated to trip all three phases
Restricted ground fault 1 has picked up
Restricted ground fault 1 has operated
Restricted ground fault 1 has dropped out
Same set of operands as shown for RESTD GND FT1
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
Stub bus is operated
