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:
The Capacitor Voltage Power Loss (P loss) can be calculated using the following formula: C is the capacitance in farads (F). V is the effective voltage across the capacitor in volts (V). f is the frequency in hertz (Hz). DF is the dissipation factor, also known as the quality loss factor.
In order to understand the usage of different types of capacitors in transmission lines we must first look in different way first the effect of power factor on the power system. Because the subject is related to the power factor correction.
Capacitor Voltage Power Loss is intrinsically linked to the quality of the capacitor. High-quality capacitors typically have lower power loss. The dissipation factor (DF), which is a measure of a capacitor's inefficiency, can change with temperature and frequency, thus affecting the power loss.
Enter the **line resistance** in ohms (Ω). Click “Calculate Power Loss” to determine the power loss in the transmission lines. Electric power loss during transmission is a critical issue in power systems, affecting the efficiency and reliability of electricity delivery.
Capacitor current is the RMS voltage divided by the total impedance. 35/67.7=0.52 amps. Power dissipation in the ESR component is calculated from the RMS voltage times current times the ratio of ESR to total impedance. 35*.52* (.589/67.727)=0.16 watts. Or, use I^2 times ESR.
