Coil current transformers
Fig. 7: SCT0xxx
In order to guarantee the power transmission, current transformers need a correspondingly large measuring
core volume with decreasing primary nominal currents. The dimensions of standard current transformers
would quickly hit their limits on the basis of this physical principle. The SCT0xxx coil current transformers
with electrical isolation are specially designed for these low primary nominal currents and are used in
corresponding applications.
