Fig.170: Transformer configuration of the EL3453 for differential current measurement
The secondary current path of the differential current transformer must be connected to the terminal contacts
I
N
(and I
N'
).
For correct calculation of the differential current value, the corresponding transformer ratio must be entered
in CoE object 0xF804:12.
Example: Transformer ratio 1A:50A corresponds to value to be entered 0.02
