I know during Surge Impedance Loading maximum power is
transferred through a transmission line and also Sending end
voltage becomes equal to Receiving end voltage i.e Vs=Vr so
my question is if both end voltages are equal then how
current travels in such line hence how power is transmitted
because flow of current needs Potential difference??

Answer Posted / gopal
actually here we are dealing with phasors in AC system .and
Vs and Vr are equal in magnitude but not in phase angle.
power flows from Vs/_ᵟ to Vr/_0 according to the equation of
real power flow
P= Vs Vr Sin(ᵟ) Vs/_ᵟ - Vr/_0
------ = ---------------
Xs I
actually in phasors although their magnitude is equal but
still their difference is not zero and an appriciable
voltage difference exist between the two ends which trigger
current and hence power to flow,
