Yy T ransformer (mask) (link)-

This component implements a two-winding, three-phase transformer in star-star connection with a three-leg or five-leg core. The type may be YyO, Yy2, Yy4, Yy6, Yy8 or Yy10 depending on the phase lag of the secondary side.

The core saturation characteristic is piece-wise linear. To model a transformer without saturation enter 1' as magn. current values and the magnetization inductance as flux values. A stiff solver is recommended if Rfe is not infinite.
