why in some cases the receiving end voltage is higher than the sending end voltage in transmission..

Answer / xavier

This effect is due to the voltage drop across the line
inductance (due to charging current) being in phase with
the sending end voltages.

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.

Answer / nithi

ferranti effect mainly occurs in uncompensated long
transmission line during light load or no-load
condition.the main reason for this effect is production of
virtual capacitance b/w the line & earth i.e charging
current.this leads to the high voltage build-up in the
trasmission line.
