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??

actually for the transfer of active power in a ac transmission system you need phase difference between the Vs and Vr.a line loaded with its own surge impedance acts as of reactive nature only.its reactive power requirement is supplied by its own line capacitance.thus no reactive component of line current and hence highest ohmic current in the line!!!
P=(Vs*Vr/X)Sin(delta)

at meter room 50 hrc switch installed,but there are not get earthing proper,so what happen?and 11kv transformer out put going in to hrc main 400a three nog each? so earthing is require for all switch? (some customer made earthing at there home.)
Assuming that a dedicated neutral earthing transformer is provided for each GT generator, when the two generators are running in parallel, has consideration been given that the earth fault current from one generator stator winding be split between the two neutral earthing transformers? If so, what adverse impact will this have on the operation of the 59N and 27TN devices?
