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.
Series reactors are used with capacitor banks for two main reasons: Control the natural frequency of the capacitor bank and system impedance to avoid resonance or to sink harmonic current. This note is based on a realistic example and discusses the effect and consequences of different types of reactor.
Capacity [C]: capacitor capacity expressed in μF (microfarad). Nominal voltage of the capacitor [V]: the connection, in series, of capacitor and reactor causes an increase in voltage at the capacitor terminals due to the Ferranti Effect that must be considered in choosing the right component.
It has many functions that can change and improve the reactive power-related operating conditions of the power system and is often used in reactive power compensation. In simple terms, the reactor can improve the voltage distribution on the long transmission line and absorb the charging capacitive reactive power in the cable line.
In this article, we will be going through semiconductors, first, we will start our article with the introduction of the semiconductor, then we will go through holes and ele Capacitive reactance is the opposition presented by a capacitor to the flow of alternating current (AC) in a circuit. It is measured in ohms (Ω).

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 ...

Reactors in a Power System
Large capacitor banks used to correct for low power factor have very low impedance when the capacitor bank is first switched ON, and the capacitors begin charging. Low impedance means that the flow of current is very high. A reactor can be added in series to increase the reactance. The increased reactance increases the impedance and reduces the …
