Understanding the Basics of Delta Transformer Calculations Because line current of a 3-phase load is calculated by the following formula: I Line =VA÷ (E Line ×√3) I Line =150,000VA÷ (240V×1.732)= 208A per line. If you took the per line power of 50,000VA and divided by one line voltage of 120V, you would come up with an incorrect line current of 50,000VA÷ 120V=417A. Delta transformer sizing.
