Here X C = capacitive reactance of the series capacitor bank per phase and X L is the total inductive reactance of the line/phase. In practice, X C may be so selected that the factor (X L — X C) sin Φ r becomes negative and equals (in magnitude) R cos Φ r so that ΔV becomes zero. The ratio X C /X L is called "compensation factor" and when expressed as a percentage is known …
Well, maybe people rarely see this configuration; however, this trick could be used to create high-voltage bipolar capacitors. If you series-connect two equal value capacitors in series, cathode-to-cathode and use only the positive lead of each cap to connect to other part of the circuits. This trick are very often seen in audio equipments.
Capacitors can be arranged in a circuit, both in series and parallel, depending on their future application. When combined in series, the charge, Q, in each capacitor is the same. Why?

Capacitors in Series and in Parallel. Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series.
In summary, the conversation discusses the use of capacitors in parallel and series to compensate for inductive loads. While a parallel capacitor can be smaller and only needs to compensate for the fixed inductive current, a series capacitor would need to be larger and its value would have to change with load.
