Capacitors are used to recover the reactive component of
power (part of power utilized for manetization in
windings).It does not matter the source generating the
voltage is Diesel Generator,steam-driven Alternator or any
other source generating A.C supply.Capacitors are always
beneficial on AC supply if the power-factor is maintained
below Unity (using a power-factor regulating relay), on
lagging side.If power-factor is not maintained through
regulating relays then it has the tendency to go on leading
side which means ,over magnetization of windings.

why capacitance effect is predominant in underground cable transmission and inductance effect is predominant in over head line transmission?
