As we know the definition of Loss Tangent in capacitor which it is: When a sinusoidal alternating voltage is applied to an ideal capacitor, the current advances by pi/2 in phase. In the case of a practical capacitor, however, advance in phase is (pi/2 - delta), which is smaller than pi/2. “delta” is referred to as Loss Angle.
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:
Here the term C is known as Capacitance. Does the Capacitance depend upon the Voltage applied across the Capacitor? You might answer yes. But it’s not correct. Capacitance only depends upon the physical dimension, dielectric and geometry of Capacitor. In fact the value of Capacitance for a parallel plate Capacitor is given as C = E0ErA / d
The capacitor dissipation factor (DF) is one of the parameters that influence the performance of a capacitor.
