DESCRIPTION
Setting for Z3 offset (reverse) reach. This setting is only visible if ‘Z3 Offset’ is enabled in ‘GROUP x DISTANCE SETUP’.
R3 Ph. Res. Fwd. 32 25 25
From 0.05*v1/I1 to 500*V1/I1 in steps of 0.01*V1/I1
[Courier Number (impedance)]
Setting for Z3 resistive reach that defines Quad’s right hand line.
R3' Ph. Res. Rev 32 26 1
From 0.05*v1/I1 to 500*V1/I1 in steps of 0.01*V1/I1
[Courier Number (impedance)]
Setting for Z3 resistive reach that defines Quad’s left hand line. This is settable only if Phase Chars. is Quad and Z3 offset is enabled
otherwise is fixed to 25% of the right hand blinder.
Z3 Tilt Top Line 32 27 -3
From -30 to 30 in steps of 1
[Courier Number (angle)]
Setting of Z3 top reactance line gradient.

From 0.05*I1 to 2*I1 in steps of 0.005*I1
[Courier Number (current)]
Zone 3 current sensitivity.
ZP Ph. Reach 32 30 20
From 0.05*v1/I1 to 500*V1/I1 in steps of 0.01*V1/I1
[Courier Number (impedance)]
ZP Ph. Angle 32 31 70
From 20 to 90 in steps of 1
[Courier Number (angle)]
Setting of line angle for zone P.
RP Ph Resistive 32 35 20
From 0.05*v1/I1 to 500*V1/I1 in steps of 0.01*V1/I1
[Courier Number (impedance)]
Setting for ZP resistive reach.
ZP Tilt Top Line 32 36 -3
From -30 to 30 in steps of 1
[Courier Number (angle)]
Setting of ZP top reactance line gradient.
ZP Sensit. Iph>P 32 37 0.05
From 0.05*I1 to 2*I1 in steps of 0.005*I1
[Courier Number (current)]
Zone P current sensitivity.
Z4 Ph. Reach 32 40 15
From 0.05*v1/I1 to 500*V1/I1 in steps of 0.01*V1/I1
[Courier Number (impedance)]
Setting for Z4 reach. This is a common setting for Z4 time delayed and Z4 high speed elements used in blocking schemes and for current
reversal guard.
Z4 Ph. Angle 32 41 70
From 20 to 90 in steps of 1
[Courier Number (angle)]
Setting of line angle for zone 4.
R4 Ph. Resistive 32 42 15
From 0.05*v1/I1 to 500*V1/I1 in steps of 0.01*V1/I1
[Courier Number (impedance)]
Setting for ZP resistive reach.
Z4 Tilt Top Line 32 45 -3
From -30 to 30 in steps of 1
[Courier Number (angle)]
Setting of Z4 top reactance line gradient.
Z4 Sensit. Iph>4 32 46 0.05
From 0.05*I1 to 2*I1 in steps of 0.005*I1
[Courier Number (current)]
Zone P current sensitivity.
Z1 Gnd. Reach 32 51 8
From 0.05*v1/I1 to 500*V1/I1 in steps of 0.01*V1/I1
[Courier Number (impedance)]
Z1 Gnd. Angle 32 52 70
From 20 to 90 in steps of 1
[Courier Number (angle)]
Setting of line angle (positive sequence) for zone 1.
Z1 Dynamic Tilt 32 53 Enabled
Enabled
Setting that enables or disables zone 1 top reactance line dynamic tilting. If set enabled, the top line angle will be automatically shifted by
the angle difference between the fault current and negative sequence current, starting from the ‘Z1 Tilt top line’ angle setting – see the next
cell. The zone 1 is allowed only to tilt down. If Dynamic tilting is disabled, the top line will be shifted by the ‘Z1 Tilt top line’ setting
(Predetermined tilting by fixed angle).
