what is the method to calculate the voltage drop for number
of meters Example 250volts I/p at one end if the cable
length is 50 meters what could be the drop?, after 100
meters how much? needs formulae.

Answer Posted / raghavendran.r
The formula for the line voltage drop is
V = sqrt(3)*[I*L*{Rcos(phi)+Lsin(phi)}] for a three phase
system.

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened.
