Can we imagine having this class in powsybl-core? There is a lot of small code parts using complex all over Powsybl. @zamarrenolm could be interested here.

Done with powsybl/powsybl-core#2835, be careful about -1 indexing change.

PR is merged, rework needed later.

Same remark, I wonder if it is the good place for this class.

Reminder: use FortescueUtil in core.

Use WindingConnectionType from powsybl-core instead.

Why this new extension compared to existing TwoWindingsTransformerFortescue? I see that you prefer using z here than r and x already present in the extension.

Try to use the load model zip instead.

I think this object is not mature enough to go in powsybl-core. The extension LineAsymmetrical should stay here too because it depends on this connector.

How do you know the type of a bus "wye" or "delta?
Then, it is unexpected that isPositiveSequenceAsCurrent is an input data. Same remark for isFortescueRepresentation.

Do you have some documentation about this attribute? I know what is a step-up transformer and a step-down transformer, but I am not sure it is what we mean here.

And what is the second option?
