The current value of the CT primary winding must be equal to or slightly greater than the size of
the mains switch of the installation. Therefore, the CT must be able to measure the maximum
current expected to be consumed by all the loads being compensated.

Figure 11: Installation of external current transformers (CT).
The connection point of the CT for a capacitor bank that compensates an entire installation is
after the mains switch of the installation.
To prevent excessive attenuation of the signal, it is recommended that the minimum secondary
section winding cable size (terminals S1, S2) is at least 2.5 mm
