Raytech CAPO 2.5 - Simplifications for Small Dissipation; Power Factor

Preliminary
6.2.3.1 Simplifications for small Dissipation / Power Factor
If the dissipation / power factor is small, the error can be neglected and you can use the following
simplifications:
For tan δ < 3%, the difference between PF and tan δ is smaller than 0.1%
where:
Cs serial Capacitance [F]
Cp parallel Capacitance [F]
Z Impedance [Ω]
Xs serial reactance [Ω]
Xp parallel reactance [Ω]
Rs serial Resistance [Ω]
Rp parallel Resistance [Ω]
