Description
Distance protection: Forward fault detected not filtered
(Directional Forward decision made by Distance logic
without any filter by Distance Start or Zone: Picks up
faster than Dist Fwd)
Distance protection: Reverse fault detected (default
PSL: LED7)
Set to 1: Directional Reverse detected in distance
algorithms (Deltas or Conventional) AND (Distance
Start)
Set to 0: With reset of Any Start/Dist Start
Distance protection: Reverse fault detected not filtered
(Directional Forward decision made by Distance logic
without any filter by Distance Start or Zone: Picks up
faster than Dist Fwd)
Distance scheme Accelerating
Distance scheme Blocking
Distance scheme Permissive
Distance protection schemes - Signal Send (default
PSL: Relay 05)
Distance protection started on phase A
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 10ms
requested)
Distance protection started on phase B
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 10ms
requested)
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 10ms
requested)
Start of distance protection for phase to ground fault
Distance protection: Phase A trip
Set to 0: Reset Dist Trip signal (fixed pulse duration is
80ms)
Distance protection: Phase B trip
Set to 0: Reset Dist Trip signal (fixed pulse duration is
80ms)
Distance protection: Phase C trip
Set to 0: Reset Dist Trip signal (fixed pulse duration is
80ms)
Unblock main channel received
Internal Carrier Received signal (main Distance
unblocking signal) received.
Signal (carrier sent by zone) received on main channel
for distance scheme logic (depending on the 'Distance
scheme' setting: Program mode / Standard mode)
Distance scheme channel out of service / Loss of
Guard (Carrier out of service)
