The capacitor bank is the most well-known solution for reducing reactive power and has been used for decades. The capacitor bank is - as the name implies - a cabinet full of capacitors with which the reactive power for the coil is supplied. As a result, the reactive power for the capacitor bank has disappeared and a cos-phi of 1 is measured.

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 …
