Basic Electronics – Selecting a Capacitor, Capacitor Values
In such cases, a series or parallel combination of capacitors can be used to get the desired capacitance in the circuit. When capacitors are connected in series, the equivalent capacitance is given by the following equation: 1/C series = 1/C 1 + 1/C 2 + 1/C 3 + . . . . When capacitors are connected in parallel, the equivalent capacitance is ...

Harmonic Filter Calculator
A series tuned harmonic filter is a combination of inductor and capacitor designed to trap a certain harmonic. These filters are applied in parallel with the power system and is often called shunt passive filters. For most harmonic filters in power systems, filters are tuned to 4.2 or 4.7 for trapping 5th order harmonics.
Introduction to Power Factor Correction PFC Capacitors and …
For an ideal electrical load, the power factor is equal to 1.0 (unity power factor). This means that all the power drawn by a load is used to do useful work. However, it is difficult for an actual electrical load to achieve that. The impedance for the load represented by Figure 5 is given by Equation 3, where XL is the inductive reactance and …

In configurations of this kind, serial reactors are connected to the capacitors. The serial reactors detune the circuit to a frequency below the 5th (or 3rd) harmonic, which is the most significant in a harmonic-rich environment. In Europe, detuning by a factor of 3.78
Capacitor banks in power system (part 1)
If V = 1 Volt than C = Q, thus capacitance is defined as the amount of electric charge in coulomb required to raise its potential by one volt.If V = 1 Volt than C = Q, and Q = 1 Coulomb than C = 1 Farad thus one Farad is capacitance of a capacitor which stores a charge of one coulomb when a voltage of one volt is applied across its terminal.
What are capacitors and reactors?
