how to Define the transformer Primary & Secondary tuns in SIMetrix ?

Hello,

I am using the center-tapped transformer in SIMetrix simulation tool. The exciting tuns ratio of the transformer are 8:2. The primary tuns I have set to 8 turns according to the ratio.
Now, what value I have to give to the Ratio to primary 1 ? (See in the attachment)
Is the value of 250m or 2 according to ratio?

I am not familiar with SIMetrix, but I think you should enter .25, because that is the ratio of 8:2.

If you were to enter 2, I believe you would step up the voltage 2x.

Sometimes in a case like this, it's a good idea to run a test simulation on your transformer. Apply a simple sinewave, and watch the output, whether it is stepped up or down.
