The most commonly used devices for reactive power compensation are shunt capacitor banks. Reactive power compensation by means of shunt capacitors in the presence of voltage harmonics increases the harmonic distortions in the system. Capacitors are branches with low impedances at frequencies of higher harmonics and they can increase the level ...

Fortunately, capacitors are relatively simple devices. There is only one way to shunt a capacitor across a transmission line, since it is a two-terminal device. Instead of thinking of the device as a capaci-tor, it is easier to consider it a block of impedance. When it is shunted across the transmission line,
the capacitor should be selected as below: If the reactance rate of the reactor is 6% or 7%, the rated voltage of the capacitor should be 0.45kV or 0.48kV, if the reactance rate of the reactor is 12% or 14%, the rated voltage of the capacitor should be 0.525kV.
