Description
Current transformers supervision indication: Indicates a
CT Fail detected after time delay has elapsed is issued
Manual (control) close in progress - using CB control
(time-delay manual closing delay in progress).
Alarm for capacitive voltage Transformer: Indicates the
residual voltage is greater than the threshold adjusted
in the settings, during a time-delay greater than the
adjustment. That alarm is also included in the general
alarm.
Channel Aided DEF: forward fault
Channel Aided DEF: reverse fault
DEF protection schemes - Signal Send
(Default PSL: Relay 05)
Channel Aided DEF: start phase A
Channel Aided DEF: start phase B
Channel Aided DEF: start phase C
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
Channel Aided DEF: trip phase A
Default PSL: Relay 09
Channel Aided DEF: trip phase B
Default PSL: Relay 09
Channel Aided DEF: trip phase C
Default PSL: Relay 09
Unblocking DEF channel
internal Carrier Received signal (main Directional Earth
Fault unblocking signal) received.
Signal received on main channel for DEF scheme logic
(depending on settings: Aided DEF/Scheme logic)
Selected as shared by default – Can operate as an
independent scheme with a separate opto input from
Dist
Default PSL: Opto Label 1
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
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
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
