Selecting the CT Rating and Cable Section:
The load on a CT should be kept to a
minimum in order to minimize the phase
shift effect of the current transformer.
Phase shift in a CT will cause erroneous
power and power factor readings,
although amp readings are correct.
It is advised CT rating be selected from
this table for the best measurement
accuracy.
Selecting the CT Accuracy Class:
The CT accuracy class should be selected in accordance with the required measurement precision. The
accuracy class of the controller is %0.5. Thus %0.5 class CTs are advised for the best result.
