EDR-3000 IM02602003E
The screen shot above shows the adaptive setting configurations following applications based on only one simple
overcurrent protection element:
1. Standard Set: Default settings;
2. Adaptive Set 1:
SOTF
application (Switch-OnTo-Fault);
3. Adaptive Set 2:
CLPU
application (Cold Load Pickup);
Application Examples
The output signal of the
Switch OnTo Fault
module can be used to activate an
Adaptive Parameter Set
that
sensitizes 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). This applies to devices
that offer voltage protection only.
The ground overcurrent protection can be modified by the residual voltage. This applies to devices that offer voltage
protection only.
Dynamic and automatic adaption of the ground current settings in order to adapt the settings to different loads
(single-phase load diversity).
Adaptive Parameter Sets are only available for devices with current protection
modules.
