Example of the Threshold Value of the Definite Time-Overcurrent Protection (Edit Mode:
Secondary)
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 current-transformer ratio changes from 1000 A/1 A to 1000 A/5 A. Change the secondary
rated current of the current transformer in the setting sheet of the transformer data from 1 A to 5 A (Edit
mode: Secondary). If you change the transformer data, a window will appear (see the following figure) that
will ask you for the action desired.
