Customer ServiceCapacitor 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.
There was a notable reduction in active power losses (I2R losses) throughout the distribution lines. The optimized capacitor placement minimized the current flow, thereby reducing resistive losses. Capacitors provided local reactive power support, reducing the amount of reactive power that needed to be transmitted over long distances.
The measured current and voltage values are stored in a high-speed sampling digital recorder (sampling frequency: 100 MHz, resolution: 16 bits). The values are transferred to the computer, and the capacitor loss during one switching period and the average capacitor loss value in steady state are calculated by the loss calculation software.
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.
In ceramic capacitors, metal losses mainly depend on the characteristics of the materials and construction. Skin effect is a common energy loss mechanism in electrodes and terminations of ceramic capacitors. This energy loss mechanism is frequency-dependent. Excessive metal losses can cause heating and thermal breakdown in ceramic capacitors.
