23.2: Reactance, Inductive and Capacitive
For capacitors, we find that when a sinusoidal voltage is applied to a capacitor, the voltage follows the current by one-fourth of a cycle, or by a (90^o) phase angle. Since a capacitor can stop current when fully charged, it limits current and offers another form of AC resistance; Ohm''s law for a capacitor is [I = dfrac{V}{X_C},] where (V) is the rms voltage across the capacitor.

Get a quote6 FAQs about [How to choose reactors and capacitors]
Should reactors be placed above capacitors?
The next requirement for the reactors is to be placed above the capacitors, since they evolve much more heat than capacitors which is lighter and could go up causing the capacitor temperature to rise. If one wants to place the reactors in the same cubicle, they should be physically separated by a barrier.
What is the difference between a reactor and a capacitor?
Capacitors are transposed and placed when arranged one below the other in racks. This arrangement gives better cooling to all capacitors equally. Capacitors are sensitive to high temperature and hence proper care will have to be taken while locating them. Reactors operate at much higher temperature than capacitors.
Do reactors have to be associated with capacitor banks for power factor correction?
Reactors have to be associated to capacitor banks for Power Factor Correction in systems with significant non-linear loads, generating harmonics. Capacitors and reactors are configured in a series resonant circuit, tuned so that the series resonant frequency is below the lowest harmonic frequency present in the system.
How to choose a MCCB capacitor & detuned reactor?
Make sure to set the thermal setting of the MCCB according to the kvar rating. Network characteristics, and in particular network harmonic distortion, must absolutely be taken into account when choosing capacitors and detuned reactors (if any).
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 are APFC reactors & capacitors?
Reactors: Reactors are used in steps as detuned filters and are connected in series with capacitors. It must be designed to withstand fundamental and harmonic currents. Capacitors: Capacitors forms the core component in APFC equipment and plays a vital role in power factor correction.
