Description
Distance scheme channel out of service / Loss of Guard
(Carrier out of service)
DEF scheme channel out of service / Loss of Guard
Selected shared by default – Can operate as an
independent scheme with a different opto input from Dist
Default PSL: Opto Label 2
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
Fuse failure on busbar VT or MCB open (blocks voltage
dependant functions), If it is linked to an opto input in the
PSL and energised, the DDB signal informs the P44x
about an internal maloperation from the VT used for
synchronisation check (see Check Synchronism logic
section).
Fuse failure on line VT or MCB open (blocks voltage
dependant functions). If it is linked to an opto input in the
PSL energised, the DDB informs the P44x about an
internal maloperation from the VT used for the
impedance measurement reference (line in this case
means Main VT ref measurement, even if the main VT is
on the bus side and the Synchronism check VT is on the
line side).
Block earth fault stage 1 time delay
Set to 1: 'IN>1 Time Delay' will be blocked & IN>1 will
start but will not issue any trip command.
Reset to 0: opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
Block earth fault stage 2 time delay
Set to 1: 'IN>2 Time Delay' will be blocked & IN>2 will
start but will not issue any trip command.
Reset to 0: opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
Block earth fault stage 3 time delay
Set to 1: 'IN>3 Time Delay' will be blocked & IN>3 will
start but will not issue any trip command.
Reset to 0: opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
Block earth fault stage 4 time delay
Set to 1: The IN>4 time-delay will be blocked & IN>4 will
start but will not issue any trip command.
Reset to 0: opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
Block aided DEF time delay
The DEF time-delay will be blocked & DEF will start but
will not issue any trip command.
Reset to 0: Opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
Block phase overcurrent stage 1 time delay
Set to 1: 'I>1 Time Delay' will be blocked & I>1 will start
but will not issue any trip command.
Reset to 0: opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
Block phase overcurrent stage 2 time delay
Set to 1: 'I>2 Time Delay' will be blocked & I>2 will start
but will not issue any trip command.
Reset to 0: opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
