3phase Derived Reference

Hi there,
I have installed one VT and 3 Cts on a 3 phase system.
I was trying to set the derived reference on the Cts as per documentation :

But on my system the option to select the main phase to witch the voltage is referring to, is not there.


Am I missing something?

Thanks for helping

Click Setup->Inputs and check “Enable derived three-phase” at the bottom.
