Engineers widely use the “2/3 rule” for sizing and placing capacitors to optimally reduce losses. Neagle and Samson (1956) developed a capacitor placement approach for uniformly distributed lines and showed that the optimal capacitor
Shunt reactors and capacitors as well as series capacitors are passive compensation devices: they can be permanently connected or they can be switchable. In the first case, these devices are designed as part of the basic grid, the one to be controlled; in the second, they are part of control resources that support basic grid voltages by recovering voltage
Material selection is another critical aspect to address in the method statement. Capacitor banks are comprised of various components such as capacitors themselves, reactors or inductors if required, discharge resistors for safety

A damping reactor is mainly connected in series with several capacitor banks. It is created to limit the inrush current while it also has the capability to resist the fault, as well as, the rated current in the event of a short circuit. with regards to its installation, a damping reactor may be further classified as: Conventional dry type

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 times the line frequency is most common, whereas in other parts of the world, in
In both cases the reactors are set in series with the bank of three-phase capacitors and types can be made for either indoor or outdoor installation. The “filter” reactors are used with the aim of reducing the factor of distortion; the
Three locations can be selected for the series capacitor. (i) Location along the Line – When there is a bank of capacitors at the time of installation, the capacitor bank is placed in the middle of the line, and when
The rejection reactors of the REZ / RBEZ series have been specifically designed for use in static capacitor banks in installations with a high harmonic content. The reactors must be connected in series with each capacitor for adequate protection of the capacitors and the static operations module, and to avoid resonance effects in the installation.

The capacitor-reactor assembly absorbs the portion of the current of the 5th order harmonic and acts as a detuned filter for higher frequencies. In some installations, other values of p% are required, for example 5.6% (210 Hz), 6% (204 Hz), 14% (134 Hz), etc. CIRCUTOR can build reactors on demand, which will be adapted to any power rating, p%, voltage and frequency.

Reactors may be used as line or load reactors (see Figure 1). Line reactors are used when low line impedance allows high inrush current, when power factor correction
In the distribution systems, the power factor correction capacitors are usually installed on thepoles. These installations are similar to the pole-mounted distribution transformers. The interconnections are made using insulated power cables. Pole-mounted capacitor banks can be fixed units or switched units to meet the varying load conditions.
In industrial and distribution systems, capacitor banks are usually installed at 4.16 kV. Note that voltage ratings may vary from country to country. Let's discuss now the most important locations where shunt capacitor banks are usually being installed. 1. Pole-mounted capacitor banks
Depending on the need, the capacitor banks are installed at extra-high voltage (above 230 kV), high voltage (66–145 kV), and feeders at 13.8 and 33 kV. In industrial and distribution systems, capacitor banks are usually installed at4.16 kV. Note that voltage ratings may vary from country to country.
Calculate the capacitor KVAR. We should choose a capacitor with nominal voltage Un higher than Uc. A capacitor with nominal power of 25 KVAR at 480 V, calculate the effective Capacitor KVAR if a detuned reactor will be used at 400 V. noting that p =14%.
Power factor correction capacitor banks can be configured in the following ways: Delta connected Bank. Star-Solidly Grounded Bank. Star-Ungrounded Bank. Go to Content ↑ 1. Star-Solidly Grounded Initial cost of the bank may be lower since the neutral does not have to be insulated from ground.
The reactive power supplied by the capacitor bank can be adjusted according to variations in the power factor and the load of the receivers. These capacitor banks are made up of a combination of capacitor steps (step = capacitor + contactor) connected in parallel.
