There are many examples - look into protection relay example

Thanks for the reply. I found a protection example where they first wire 3-phase signals input the FFT block, and then the output inputs the ABC --> + - 0 block. So, I used the same approach as you can see in the picture attached.
I still have 2 questions:
1. Why is it necessary to use the FFT for this?
2. The magnitude of the zero-sequence current in the plots looks like is shown as space vector (current-phasor) as you don't see it having a periodic (sine) form. What if I want to have this plot as instant values?
Thanks,
