Description
If linked to an opto input in a dedicated PSL and
energised, it indicates that external synchronism
conditions are met – This can be linked afterwards to an
internal autoreclose logic
Dead Line: high when the Dead Line condition is met
(voltage below the 'V< Dead Line' threshold value
(setting) – The measured voltage is always calculated as
a single phase voltage
Live Line: high when the Live line condition is met
(voltage above the 'V> Live Line' threshold value
(setting) - always calculated as a single phase voltage
reference.
Dead Bus: high when the Dead Bus condition is met
(voltage below the V<Dead Bus threshold value (setting)
- always calculated as a single phase voltage reference.
Live Bus: high when the Live Bus condition is met
(voltage above the V>Live Bus threshold value (setting)
- always calculated as a single phase voltage reference.
Manual (control) close in progress - using CB control
(time-delay manual closing delay in progress).
Distance protection schemes - Signal Send (default
PSL: Relay 05)
Unblock main channel received
Internal Carrier Received signal (main Distance
unblocking signal) received.
Distance protection: Forward fault detected (default PSL:
LED6)
Set to 1: Directional Forward 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 (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: Phase A trip
Set to 0: Reset Dist Trip signal (fixed pulse duration is
80 ms)
Distance protection: Phase B trip
Set to 0: Reset Dist Trip signal (fixed pulse duration is
80 ms)
Distance protection: Phase C trip
Set to 0: Reset Dist Trip signal (fixed pulse duration is
80 ms)
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 10 ms
requested)
