8.4.3.2 Setting example for generator application
In case of out of step conditions this shall be checked if the pole slip centre is inside
the generator (zone 1) or if it is situated in the network (zone 2).

If the apparent impedance crosses the impedance line ZB – ZA this is the detected
criterion of out of step conditions, see figure 141.
