The parameter sets the transformation ratio for the external CT input of device M or E1 or E2. External current transformers of up to
3275.0 A can be used on the secondary circuit, equivalent to 5.0 A (full scale) x 655 (max. transformation ratio).
1...655
min...max:
Example: You have a 1000 A : 5 A external transformer. The transformation ratio to be set in parameter r.tA is therefore 1000/5 = 200.
