Question
How to calulate Voltage Drop for perticular lentgh of 
busbar (Cu/ Al)?
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
e=eo*E^((-.5*(R/Zs)+(Zs+G))*x)
e=voltage wave after travelling X Km
e0=initial value
Zs=surge impedance
R=resistance/Km
G=leakage/Km
E=Naperian base
