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.



what is the method to calculate the voltage drop for number of meters Example 250volts I/p at one ..

Answer / raghavendran.r

The formula for the line voltage drop is

V = sqrt(3)*[I*L*{Rcos(phi)+Lsin(phi)}] for a three phase
system.
