Connection example with external protection device for 3-pole reclosure; AR
control mode = with TRIP
But if the internal automatic reclose function is controlled by the
pickup
(only possible
for three-pole tripping:
110
Trip mode
=
3pole only
), the phase-dedicated pickup
signals of the external protection must be connected if distinction shall be made
between different types of fault. The general trip command then suffices for tripping
(No. 2746). Figure 2-128 shows a connection example.
