Using capacitors to supply reactive power reduces the amount of current in the line. Since line losses are a function of the current squared,I2R, reducing reactive power flow on lines significantly reduces losses. Engineers widely use the “2/3 rule” for sizing and placing capacitors to optimally reduce losses.
Capacitor Losses (ESR, IMP, DF, Q), Series or Parallel Eq. Circuit ? This article explains capacitor losses (ESR, Impedance IMP, Dissipation Factor DF/ tanδ, Quality FactorQ) as the other basic key parameter of capacitors apart of capacitance, insulation resistance and DCL leakage current. There are two types of losses:
Excess losses can cause the dielectric to heat leading to thermal breakdown and capacitor failure. In ceramic capacitors, dielectric losses are predominant at low frequencies. At high frequencies, these losses diminish and their contribution to the overall ESR is negligible. Metal losses comprise of ohmic resistance losses and skin effect.
Most noticeably, capacitors reduce losses, free up capacity, and reduce voltage drop. Let’s go a little bit into details. By canceling the reactive power to motors and other loads with low power factor, capacitors decrease the line current. Reduced current frees up capacity; the same circuit can serve more load.

In most capacitors, electromechanical losses occur mainly within the dielectric material and the internal wiring. In the dielectric material, electromechanical losses are primarily caused by electrostriction. In some cases, it may be caused by piezoelectric effect. In internal wiring, Lorentz forces can cause flexing.
