Operand description
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

Stage 1 of the sub-harmonic stator ground protection has picked up
Stage 1 of the sub-harmonic stator ground protection has dropped out
Stage 1 of the sub-harmonic stator ground protection has operated
Stage 2 of the sub-harmonic stator ground protection has picked up
Stage 2 of the sub-harmonic stator ground protection has dropped out
Stage 2 of the sub-harmonic stator ground protection has operated
Ground over current element of the sub-harmonic stator ground protection
has picked up
Ground over current element of the sub-harmonic stator ground protection
has dropped out
Ground over current element of the sub-harmonic stator ground protection
has operated
Sub-harmonic stator ground module trouble has picked up
Sub-harmonic stator ground module trouble has dropped out
Sub-harmonic stator ground module trouble has operated
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 5 disturbance detector has operated
Source 6 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,
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
The summator 1 result is greater than the summator 1 pickup
The summator 2 result is greater than the summator 2 pickup

The summator 6 result is greater than the summator 6 pickup
