Diagr. Measurement with Amperemeter in series
Diagr. Measurement via sum current transformers
Current measurement
The current measurement is carried out via ../5A or ../
1A current transformers.
If the current must be measured with an Amperemeter
additionally to Prophi, it must be connected in series.
Sum current measurement
If Prophi is connected to a sum current transformer, the
total transformation ratio must be programmed.
Attention!
For unequal load of the outer conductors, the
current should be measured in the outer con-
ductor, which is loaded most heavily.
