6 FAQs about [Capacitors and reactors]

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 dissipation power of a capacitor?

d over voltage and harmonic content. Depending on the detuning factor, actual dissipation power of o r reactors is between 4 and 6W/kvar.While using capacitors and reactors within a capacitor bank, suitable means for heat dissipation and ooling of components shall be taken.A minimum 20mm distance be

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.

How much inrush current should a capacitor bank have?

In accordance with IEC 60871-1, the inrush current should be limited to 100 times the rated current of the capacitor bank. When a capacitor bank is initially connected to a voltage source, the transient charging current will flow, attempting to equalize the system voltage and the capacitor voltage.

What are the different types of reactors?

This article highlights two common types of reactors which are the dry-type and the oil-immersed. In an AC circuit, reactance is the opposition to current flow. 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.
