Parameters
Application Examples
•
The output signal of the
Switch Onto Fault
module can be used to activate an
Adaptive Parameter Set
that sensibilizes the overcurrent protection.
•
The output signal of the
Cold Load Pickup
module can be used to activate an
Adaptive Parameter Set
that desensitizes the overcurrent protection.
•
By means of
Adaptive Parameter Sets
an Adaptive
Auto Reclosure
can be realized. After a reclosure
attempt the tripping thresholds or tripping curves of the overcurrent protection can be adapted.
•
Depending on undervoltage the overcurrent protection can be modified (Voltage Controlled).
•
The earth overcurrent protection can be modified by the residual voltage.
•
Matching the ground current protective settings dynamically and automatically according to the single-
phase load diversity (Adaptive relay Setting – Normal Setting/Alternative Setting)
Adaptive Parameter Sets are only available for devices with current
protection modules.
