The following setting example shows how you can change the transformer ratio in DIGSI 5, and what impact
this has on the settings in the setting views Primary and Secondary. The setting is seen in the example of the
3-phase voltage/current function.
The following output data are assumed:
Voltage transformer: 400 kV/100 V
Threshold value dM/dt falling: 20 V
The following figure shows the setting of the trigger function Trig. V Fund. in the secondary view. The
threshold value of the stage is set to 20 V.
