Description
Control close command from user (by internal CB
control)
Instantaneous unconfirmed fuse failure internal
detection. Set high for internal Fuse Failure detection
made with internal logic.
CB Phase A status (from internal logic and CBAux opto
inputs state: 1 = CB-Pole A is open.
This signal is used for Any Pole Dead & All Pole Dead
internal detection.
CB Phase B status (from internal logic and CBAux opto
inputs state: 1 = CB-Pole B is open.
This signal is used for Any Pole Dead & All Pole Dead
internal detection.
CB Phase C status (from internal logic and CBAux opto
inputs state: 1 = CB-Pole C is open.
This signal is used for Any Pole Dead & All Pole Dead
internal detection.
Any circuit breaker pole dead (one or more poles open,
pole status detected by CBaux or internal thresholds). If it is
linked in the PSL, the DDB:'Any Pole Dead' signal
indicates that one or more poles are open.
Any Pole Dead = Pole Dead A OR Pole Dead B OR Pole
Dead C
All circuit breaker poles dead (breaker open 3 phase,
pole status detected by Cbaux or internal thresholds). If it is
linked in the PSL, the DDB:'All Pole Dead' signal
indicates that all poles are dead (3 poles are open).
All Pole Dead = Pole Dead A AND Pole Dead B AND Pole
Dead C
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 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: Internal characteristic
Set to 1: logic with Distance Start at 1 (Minimum 1 loop
has been detected in the quadrilateral characteristic)
Set to 0: Reset of (R, X) (resistance, reactance)
calculation made by the All pole Dead detection
Cross Country Fault
Set to 1: The cross country logic is activated (1 Fault
Fwd/1 Fault Rev detected)
Zero Sequence Power - Start: The ZSP START cell at 1
indicates the Zero Sequence Power function has started
- in the same time, it indicates the timer-delays
associated have started and are running (fixed one first
and then IDMT timer)
Zero Sequence Power - Trip: The ZSP TRIP cell at 1
indicates the Zero Sequence Power function has
performed a trip command (after the start and when
associated timers are issued)
Z1 decision not filtered by phase selection
Start of an Out of Step Detection (1st cycle), The first out
of step cycle has been detected (Zlocus in/out with the
opposite R sign) & the « Out Of Step start » picks-up
Start of Stable Swing (1st cycle): The first stable swing
cycle has been detected (Zlocus in/out with the same R
sign) & the « Stable Swing start » picks-up
