‘Ydy T ransformer (mask) (link)-

This component implements a three-winding, three-phase transformer in star-delta-star connection with a three-leg or five-leg core. The secondary side rnay be of type d1,d3, d5,61, d9 or dli; the terliary side may be of typeyO, y2, y4, d6, d3 or d10 depending on the specified phase lag.

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.
