How to setup a Stepdown Transformer in Proteus-for simulation

How to setup a Step down Transformer, with 230v primary input and 6 volt secondary output in Proteus ?

Dow does the calculation ?
 

Assumed L1 is 1mH then L2 is 680mh ,Not working
 

If you use 1 H for the primary and 680 uH for secondary, it should be close.
1/(230/6)^2=[680.5293u]

Yes. Besides correct voltage ratio, the magnetizing inductance should be scaled appropriately. 1 H means 0.73 A magnetizing current, expectable for a 10 or 20 kW transformer.
 
Thanks its correct if L1 = 1H
L2 = 680.53uH
