Question { Genco, 42970 }

what is the difference between series and shunt compensation
using facts in a transmission line


Answer

compansation means to overcome from
losses.

the line voltage by connecting an
inductor in series in line.
Parallel compansation is improve the
power factor by connecting capacitor in
parallel to load
