Description
Fuse failure indication (VT alarm). High when the opto
input is energised (copy of MCB) OR an internal Fuse
Failure is confirmed when the VTS timer elapses.
Instantaneous unconfirmed fuse failure internal
detection. Set high for internal Fuse Failure detection
made with internal logic.
Phase A trip on weak infeed
Phase B trip on weak infeed
Phase C trip on weak infeed
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)
Z1 decision not filtered by phase selection
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
10)
Zone 1 Extension Input
Opto input energized if linked by PSL OR any internal
DDB by dedicated PSL
At 1: Signal will initiate Z1 extension logic if selected
(setting).
This DDB can be assigned to any external/Internal
condition for starting Z1X logic
Fault in zone 2 (convergence of loop in Z2) and filtered
by blocking/unblocking Power Swing/Reversal guard

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 - Timer Block: If assigned to an
opto input in a dedicated PSL, Zero Sequence Power
function will start, but will not perform a trip command -
the associated time-delay (adjusted with 'K Time Delay
Factor ' setting, will be blocked
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)
Load Blinder Detection in Loop AN: Cell at 1 indicates
the Impedance is located within the AN loop Load
Blinder Region.
