Threshold-Value Setting in an Example of the Current Transformer
If you only want to work in the secondary view, DIGSI 5 supports you if the transformer ratio changes during
the project phase.
In the example the following parameters are set according to the current transformer ratio of 1000 A/1 A . The
parameter dM/dt drop (/Filter time) has a setting value of 0.300 A (see the following image).
