    dear anyone

     I need someone who can adviced me some solfware for calculate sizing of cable and voltage drop in eletrical system.

       I will appreciate for your kindness.

        best regard

    voltage drop formula- root3*VI(rcos(fie)+jxsin(fie))*L(where L is in KM).

    THIS FORMULA DIFFER ACORDING TO LENGTH OF TRANSMISSION LINE: FOR SHORT TRANSMISSION LINE IT IS                                                    V (DROP)=Iz   Z   IS impedance   and it is for single phase so, for balance 3-phase it s multiple of three
