Shunt Capacitors and Reactors

Shunt capacitors are used to compensate lagging power factor loads, whereas reactors are used on circuits that generate VArs such as lightly loaded cables. The effect of these shunt devices is to supply or absorb the requisite reactive

Reactor Reactance in Power System Explained

Capacitor banks are used to improve the power factor of electrical systems by providing capacitive reactance, which counteracts the effects of inductive reactance. However, without proper management of eactance, introducing capacitor banks can create resonance conditions, leading to harmonic distortions.

Capacitors and Power Factor Correction System: Single Phase Reactor

The reactors are single phase with an air core and copper winding and they are set in series with the bank of capacitors; they can be made for either indoor installation or outdoor installation. The reactors must be installed on post insulators with an insulation class equal to or greater than that of the bank of capacitors, considering the

Reactors in a Power System

A reactor, also known as a line reactor, is a coil wired in series between two points in a power system to minimize inrush current, voltage notching effects, and voltage spikes. Reactors may be tapped so that the voltage across them can be changed to compensate for a change in the load that the motor is starting. Reactors are rated by the ohms

6 FAQs about [Capacitor Reactor ]

How do I determine if a capacitor or reactor is suitable?

It is then necessary to verify that the selected capacitors and reactors are suitably sized to limit inrush currents to less than a predefined maximum magnitude, which, for example, is 100 times the rated current, according to IEC 60871-1.

Why do block reactors need capacitor banks?

One of the unwanted effects is the overheating of capacitor banks that are needed to maintain the power factor within the parameters required by the power authority, with a resulting, significant reduction in the average working life. The ideal solution is to insert block reactors in series with capacitor banks.

What is the function of a capacitor?

The capacitor has the function of "connecting AC and isolating DC", that is, in the AC circuit, the frequency characteristic of capacitive reactance is used to "connect high-frequency AC and block low-frequency DC". Capacitors are capacitive loads, mainly used to compensate reactive power and store energy.

What types of reactors are used in a power system?

The common reactors used in the power system areseries reactors and parallel reactors. The series reactor is mainly used to limit the short-circuit current, and it is also used in series or parallel with the capacitor in the filter to limit the higher harmonics in the power grid.

What is the rated voltage of a capacitor?

In general, the rated voltage of the partial compensation capacitor is calculated according to the photographic voltage, and the rated voltage of the common compensation capacitor is calculated according to the line voltage. Generally, capacitors are required to be able to withstand at least1.1 times the working voltage.

How are reactors rated?

Reactors are rated by the ohms of impedance that they provide at a given frequency and current. Reactors may also be rated by the I2R loss across the device at a certain frequency at a rated current. Two common types of reactors are the dry-type and the oil-immersed. The dry-type is open and relies on the air to circulate and dissipate the heat.
