11.2.6 Operation principle
11.2.6.1 Current reversal logic
The current reversal logic uses a reverse zone connected to the input IREV to recognize the fault on
the parallel or any other outgoing line in any of the phases. When the reverse zone has been
activated for a certain settable time
and activation of trip signal for a predefined time
signal to reset before the trip signal is activated due to the current reversal by the forward
directed zone, see figure 183.
