The Ferranti Effect is a rise in voltage occurring at the
receiving end of a long transmission line, relative to the
voltage at the sending end, which occurs when the line is
charged but there is a very light load or the load is
disconnected.
This effect is due to the voltage drop across the line
inductance (due to charging current) being in phase with
the sending end voltages. Therefore both capacitance and
inductance are responsible for producing this phenomenon.[1]
The Ferranti Effect will be more pronounced the longer the
line and the higher the voltage applied.[2] The relative
voltage rise is proportional to the square of the line
length.[3]
Due to high capacitance, the Ferranti Effect is much more
pronounced in underground cables, even in short lengths.[4]
