Description
Distance protection started on phase C
Set to 0: Reset of (R, X) (resistance, reactance)
calculation made by All pole Dead detection:
– I Dead: Fourier algorithm calculation (3 or 4 samples
requested)
– V Dead calculated by CB Fail (More than 10 ms
requested)
Distance scheme Accelerating
Distance scheme Permissive
Distance scheme Blocking
Fault in zone 1 (convergence of loop in Z1)
Set to 0: Reset of (R, X) (resistance, reactance)
calculation made by All pole Dead detection
(default PSL: LED 5, Relays 01 / 10)
Fault in zone 1 extended Z1x (convergence of loop in
Z1x) and filtered by blocking/unblocking Power
Swing/Reversal guard logic (default PSL: LED 5, Relay

Fault in zone 2 (convergence of loop in Z2) and filtered
by blocking/unblocking Power Swing/Reversal guard

Distance time-delay in zone 1 tZ1 elapsed (1 = end of
timer)
If T1=0 picks up when the relay starts (Distance Start or
preset)
Distance time-delay in zone 2 tZ2 elapsed (1 = end of
timer)
Distance time-delay in zone 3 tZ3elapsed (1 = end of
timer)
Distance time-delay in zone 4 tZ4 elapsed (1 = end of
timer)
Distance time-delay in zone p tZp elapsed (1 = end of
timer)
Phase A trip on weak infeed
Phase B trip on weak infeed
Phase C trip on weak infeed
Power swing detected (3 single phase loop inside the
quad & crossing the ∆R band in less than 5ms in a 50
Hz network). Power swing is present either with out of
step cycle or stable swing cycle.
