Switch Function
SGF3/1 Disabling of element 59P-2 or 47
SGF3/2 Disabling of element 27P-2 or 27D
SGF3/3 Disabling of element 59N-1
SGF3/4 Disable of element 59N-2
When the switch is in position 1, the element is disabled.

Switch Function
SGF4/1 Selecting single-phase or three-phase use
0 = three-phase use
*
1 = single-phase use
*
SGF4/2 Internal blocking of pickup and trip of element 27P-1 when one of the measured phase-to-
phase voltages fall below 0.15 ×U
0 = internal blocking of pickup and trip of element 27P-1
*
1 = no internal blocking of pickup and trip of element 27P-1
*
SGF4/3 Internal blocking of pickup and trip of element 27P-2 or 27D when one of the measured phase-
to-phase voltages falls below 0.15 × U
0 = internal blocking of pickup and trip of element 27P-2 or 27D
*
1 = no internal blocking of pickup and trip of element 27P-2 or 27D
*
SGF4/4 Blocking of element 27P-1 tripping by the pickup of element 27P-2 or 27D
0 = tripping of element 27P-1 is not blocked
*
1 = tripping of element 27P-1 is blocked
*
SGF4/5 Start and trip criteria for element 59P-1
0 = element operates when one of the phase-to-phase voltages rise above the set pickup
*
value.
1 = element operates when all the phase-to-phase voltages rise above the set pickup value
*
SGF4/6 Start and trip criteria for element 59P-2
0 = element operates when one of the phase-to-phase voltages rise above the set pickup
*
value.
1 = element operates when all the phase-to-phase voltages rise above the set pickup value.

a)
When single-phase use is selected, the measured voltage has to be connected
to inputs X2.1-1 and X2.1-2. Additionally, the U
overridden and the negative phase-sequence protection mode and positive
phase-sequence protection mode are not in use.
