1.  The same as that of power transformers of the same VA rating

2.  Much greater than that of power transformers of  the same VA rating because they are designed for low ratio and phase angle errors which require large sized cores and winding conductors  

3.  Smaller than that of power transformers of the same VA rating  

4.  None of these
