tripping
for 2pole
The output signals generated by the individual zones are combined in the actual trip-
ping logic to form the trip output signals. The signal Dis.Gen. Trip is the general
trip command. The single-pole information Dis.Trip 1pL1, Dis.Trip 1pL2,
Dis.Trip 1pL3 implies that tripping will take place single-pole only. The Dis Trip
L123 signal indicates the three-pole trip command. Furthermore, the zone that initiat-
ed the tripping is identified; if single-pole tripping is possible, this is also alarmed, as
shown in the zone logic diagrams (Figures 6-34 up to 6-38). The actual generation of
the commands for the trip relay takes place in the tripping logic of the device. (refer to
Sub-section 6.22.4).
