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 …

Series compensation is most effective on the higher-voltage transmission lines (230 kV and above) because they have relatively high ratios of series X to series R; typically 7 to 20 or so. For example, the typical 345 kV line has an X/R ratio of about 10 and a 500 kV line has an X/R of about 18.
Thus, by compensating the series reactance to a certain degree, using a series capacitor, an electrically shorter line is realized and higher active power transfer is achieved. Installing a capacitive reactance in series in a long (typically more than 200 km) transmission line reduces both the angular deviation and the voltage drop, which ...
