Number of zones
The distance protection for phase-to-phase faults (ZS) includes six measuring zones and these
are termed Z1S, Z1XS, Z2S, Z3S, Z4S and Z5S. The distance protection for single-phase-earth
faults (ZG) also includes six measuring zones that are similarly termed Z1G, Z1XG, Z2G, Z3G,
Z4G and Z5G.

Selection of Forward, Reverse, or Non-directional for the respective zones
The selection of the element direction is provided with the setting [
Z*S-Dir
]. For instance, if
Forward
is set, then Z*S is set in forward direction, as shown in Figure 2.1-11 to Figure 2.1-13.
If
Reverse
is set, then Z*S is set in reverse direction, as shown in Figure 2.1-15 to Figure
2.1-17. Z*S can be set non-directional by setting
NonDir
, as shown in Figure 2.1-18 and Figure
2.1-19. The other elements can be set in a similar manner.
Elements in the reverse direction of ZG are not drawn in Figure 2.1-15 to Figure 2.1-17,
but they are similar to the ZS elements.
