4BRELAY SETTINGS
0BDEVICE CONFIGURATION
Time Delay (Ph-Gr fault) (s):
It is the time to wait since the moment of the
trip to the moment the breaker closing command is sent. It applies to phase
to ground faults.
Trip curve after closing section
allows configuring the following parameters
for each one of the four recloses, for each phase (if the “different settings by
phase option” is enabled), neutral and sensitive neutral.
Curve:
Types of families of curves available at the relay.
Curve Family:
Curve family of the type previously selected.
Time-dial (s):
Index of the selected curve.
Protection Functions Disabling
if checked the following protection functions
could be disabled when the recloser is activated:
Low Instantaneous Overcurrent (50).
High Instantaneous Overcurrent (50).
Time Overcurrent (51).
Negative Sequence Instantaneous Overcurrent (46DT).
Negative Sequence Time-Overcurrent (46IT).
Open Phase (46OP).
3.4.1.14. COLD LOAD PICKUP
The Figure 3-43 shows the configuration window for this function, which includes the
following sections.
General settings:
They apply to the complete function.
Inverse Time settings:
They apply to phase, neutral and sensitive neutral
inverse time settings.
Instantaneous settings:
They apply to phase, neutral and sensitive neutral
instantaneous settings.
