Therefore, the primary effect of the series capacitor is to minimize, or even suppress, the voltage drop caused by the inductive reactance in the circuit. At times, a series capacitor can even be considered as a voltage regulator that provides for a voltage boost that is proportional to the magnitude and power factor of the through current.

It is sometimes desirable to use a series connection of capacitors in order to be able to work with higher voltages. For example, let us assume that a 5kV power supply needs to be filtered using capacitors, and that the only available capacitors are rated at 1kV and are all of identical capacitance values.
There are both advantages and disadvantages to connecting capacitors in series together. On the plus side, the voltage rating of the series connection increases, allowing the circuit to handle higher voltage levels without risking damage to the capacitors. This feature is particularly useful in high-voltage capacitors in series applications.
To decrease the voltage drop considerably between the sending and receiving ends by the application of a series capacitor, the load current must have a lagging power factor. As an example, Figure 3a shows a voltage phasor diagram with a leading-load power factor without having series capacitors in the line.
However, when the series capacitor values are different, the larger value capacitor will charge itself to a lower voltage and the smaller value capacitor to a higher voltage, and in our second example above this was shown to be 3.84 and 8.16 volts respectively.
