Description Range Units Step Actual
Zone 3 Enable
Enable operation of Zone 3 distance
No – Yes - 1
Yes
Zone 3 direction
Zone 3 measuring direction, forward or reverse. Reverse

Forward
Zone 3 reach
Zone 3 reactive reach in secondary ohms, at set characteristic line
angle.
0.01 – 100 Ohm 0.01
8.26
1-Ph Resistive Limit Zone 3
Resistive reach in secondary ohms for Zone 3 phase-ground
quadrilateral characteristic. Note that the set resistance is the direct
loop resistance, without zero sequence compensation factor
applied. For phase A, the resistance at the R-axis is R

2-Ph Resistive Limit Zone 3
Resistive reach in secondary ohms for Zone 3 phase-phase
quadrilateral characteristic. Note that the set resistance is the
phase-phase resistance. For phase A to B, the resistance at the R-
axis is R

Zone 4 Enable
Enable operation of Zone 4 distance
No – Yes - 1
Yes
Zone 4 direction
Zone 4 measuring direction, forward or reverse. Note that when
the pilot logic “Directional Comparison Blocking’, “Weak Infeed”
and/or ‘Transient Block” is used, Zone 4 is always reverse,
regardless of this setting.
