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:
Figure 1 shows the tangent of loss angle of hypothetical ideal and real capacitors. In an ideal capacitor, the dissipation factor is zero, indicating no energy loss during operation. However, in an actual capacitor, various factors such as dielectric losses and electrode resistance contribute to a non-zero dissipation factor.
If the Capacitor had been pure then it would have taken current Ic leading by angle 90 degree but because of resistive component of dielectric, net current drawn is deviating from 90 degree by some angle δ. This angle δ is hence called Loss Angle. From the phasor diagram, it is clear that
A capacitor creates in AC circuits a resistance, the capacitive reactance. There is also certain inductance in the capacitor. In AC circuits it produces an inductive reactance that tries to neutralize the capacitive one. Finally, the capacitor has resistive losses.
Losses Impedance and ESR A capacitor creates in AC circuits a resistance, the capacitive reactance (Formula C1-3). There is also certain inductance in the capacitor. In AC circuits it produces an inductive reactance that tries to neutralize the capacitive one.
