Protection and Automation Functions
7.24 Instantaneous Tripping at Switch onto Fault
Normally, the pickups of protection functions and stages with high fault current are selected:
•
Overcurrent protection (phase and ground)
A specific protection stage is generally used. This can be one of the protection stages provided for the protec-
tion application, which itself trips with a delay. An additional protection stage with settings optimized for this
use case, for example, increased threshold value and blocking of self-tripping, can also be used.
Parameter: Operate delay
•
Recommended setting value (_:5941:6) Operate delay = 0.00 s
When switching onto a fault, the tripping should usually be instantaneous. The tripping delay is therefore set
to 0.
