Phase tap changer presence not taken into account in SLD for 3WT

[So-Fras]

Describe the current behavior

The presence of a phase tap changer is taken into account when creating the middle 2wt note (NodeFactory > createMiddle2WTNode).
The componentType of the node is different if the two-winding transformer has a phase tap changer or not (PHASE_SHIFT_TRANSFORMER vs TWO_WINDINGS_TRANSFORMER)

We can find both components in the components.json resource file.

According to the componentType, a different component will be incorporated in the svg, thus allowing to take into account the presence or not of a phase tap changer for 2wt.

With no phase tap changer (no arrow):

With a phase tap changer (symbolized by an arrow):

For three-winding transformers, there is no check to take into account the potential presence of a phase tap changer.

Describe the expected behavior

The presence of phase tap changer should be represented in the SLD for 3wt too.

The difference here is that here, each leg of a 3wt transformer could have a phase tap changer so the arrow should not be drawn in the middle of the 3wt as it is done for 2wt but on the corresponding winding (with the same color as the winding, to enhance readability).

Extra Information

The same goes for NAD diagrams:

• SvgWriter > draw2wt that calls drawPstArrow when the edge is detected as a PST_EDGE
• Nothing of the kind is done for 3-winding transformers.
