How is the three-phase transformer with three windings modelled?

No equations for the modelling of the transformer with three windings are provided in the documentation. This would be however very helpful for an exact current control design of a grid converter. Is there any documentation available?

Are you using a transformer from the Specialized Power Systems blockset? Because the transformers of the Simscape Electrical blockset seem fairly well documented here.

Indeed it is from the Specialized Power Systems Blockset: https://ch.mathworks.com/help/physmod/sps/powersys/ref/threephasetransformerthreewindings.html

This block implements a three-phase transformer by using three single-phase transformers with three windings. For a detailed description of the electrical model of a single-phase transformer, see the Linear Transformer block.
