Coil current transformers
Fig. 5: SCT0xxx
In order to guarantee the power transmission, current transformers need a correspondingly large measuring
core volume with decreasing primary rated 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 rated currents and are used in corresponding
applications.
