Answer Posted / n.r.biswas

In a long transmission line, there is a rise of voltage at
the receiving end due to no load or light loads. In long
transmission line having large capacitance which causes
large charging current in the line, occurs voltage drp in
the line, accordingly, receiving end voltage becomes
greater than the sending end voltage, the phenomenan is
called ferranti effec
Line drop = Ic(R+jX) Ic - Charging current at no load
Vr=Vs+Ic(R+jX) Ic leads Vr by an angle 90 Deg.
