There are some specific advantages of using shunt capacitors such as,
It reduces the line current of the system.
It improves the voltage level of the load.
It also reduces system Losses.
It improves the power factor of the source current.
It reduces the load of the alternator.
It reduces capital investment per megawatt of the Load.
All the above-mentioned benefits come from the fact, that the effect of the capacitor reduces the reactive current flowing through the whole system.
A shunt capacitor draws almost a fixed amount of leading current which is superimposed on the load current and consequently reduces reactive components of the load and hence improves the power factor of the system.
Series capacitors on the other hand have no control over the flow of current. As these are connected in series with the load, the load current always passes through the series capacitor bank. Actually, the capacitive reactance of the series capacitor neutralizes the inductive reactance of the line hence, reduces, the effective reactance of the line.
