Zone 1, zone 1X, zone 2 and zone F can trip on condition that zone 3 has operated, in both
characteristics.
The power swing blocking elements (PSBS and PSBG) are a combination of the reactance element
and blinder element as shown in Figure 2.5.1.4. The outer element PSBOUT encloses the inner
element PSBIN with a settable width of PSBZ.
