dyn11 transformer model needed!

[ChrisRTA]

I am looking to simulate part of or power system on multisim in order to check a problem.  I can find a 3-phase transfomer model in the components but need some help in changing its paraments.

As follows:

DYN11 transformer (Delta connected primary, star secondary and 30 degrees phase shift).  I need to know how to chane the spice code as i dont have the knowledge to myself.

Change the model so it is a step down from 33kV to 3.3kV

Any help on this would be greatly apprciated.

Regards

I never could see how the Multisim 3 phase transformer model was worth a hoot and don't know how to make it into anything useful. I have been using an array of three single-phase transformers to come up with a D-Y configuration. This is based on the virtual transformer model from older versions of Multisim. These models do not account for saturation and may be capable of doing things that a real transformer isn't - like passing through dc for instance. However, it is usable in situations where it isn't necessary to model what is going in in the transformer core; ie, saturation. The attached was done in Multisim 10.0.
