As we know due to Ferranty Effect Receiving End Voltage become greater than Sending End Voltage in Long Transmission Line.In long transmission line Between R,Y,B there is only Air. So line Capacitenc got increased in Low load Condition in the receiving End.As load will increasein Receiving End, line inductance will increase accordingly Receiving  End Voltage tend to reduce.

To overcome both the effect SVC( Static Var Compensator) is Used in Modern day T& D Lines.As well as System stability will increase.
