Principle of Tan Delta Test. When a pure insulator is connected between the line and earth, it acts like a capacitor.Ideally, if the insulating material, also serving as a dielectric, is 100% pure, the electric current passing through would only have a capacitive component, with no resistive component, due to zero impurities.. In a pure capacitor, the capacitive electric current …
When it comes to electrolytic capacitors, you may not calculate the ESR but measure it instead. As the frequency increases, the Z of the capacitor increases as the effect of L (a.k.a. ESL) increases. As given in the …
Capacitor dissipation factor (tangent of loss angle) The capacitor dissipation factor (DF) is one of the parameters that influence the performance of a capacitor.

The power dissipated in a capacitor can be calculated by multiplying the ESR by the square of the RF network current. Power dissipation in the capacitor is therefore expressed as: Pd = ESR x (RF current)2 or Pd = ESR x I 2. It is interesting to note that low loss capacitors may be used in very high RF power applications hundreds of times greater than the capacitors power rating. …
The ratio of this "power loss" to the total power supplied is the "power factor" (PF) of the capacitor. This PF figure then is a measurement factor for rating the "inefficiency" of the power transfer capabilites of the capacitor. For those capacitors where the PF figure is .1 ( 10%) or less, a ratio figure known as the "dissipation factor" (DF) is more commonly used. The reason …
The loss tangent is defined by the angle between the capacitor''s impedance vector and the negative reactive axis.
