However, the behavior of reactance differs between coils and capacitors. The reactance of a coil is called "inductive reactance," while the reactance of a capacitor is called "capacitive reactance." This section
Consider the Line reactance of the transmission line in per unit system.For 50% compensation, the value of the capacitor in the TCSC will be 50% of the line reactance. Now for capacitive compensation, the value of inductive reactance must be greater than capacitive reactance, that is, X > X X = (X * X c) / (X l – X ) (2)

Capacitor Shelf Life. Capacitor shelf life is the amount of time a capacitor can last while stored away during a period of disuse.
For capacitors in AC circuits, capacitive reactance is given the symbol Xc. Then we can actually say that Capacitive Reactance is a capacitors resistive value that varies with frequency.

Typical working voltages are 20 volts up to about 200 volts. It is a good insulator, and it has a permittivity of almost 1,000 times more than that of dry air.
Capacitive reactance is a complex number with a phase angle of -90 degrees. I hope this helps! The two factors that determine the capacitive reactance of a capacitor are: Frequency (f): The higher the frequency of the AC signal, the lower the capacitive reactance.
For capacitors in AC circuits opposition is known as Reactance, and as we are dealing with capacitor circuits, it is therefore known as Capacitive Reactance. Thus capacitance in AC circuits suffer from Capacitive Reactance. Capacitive Reactance in a purely capacitive circuit is the opposition to current flow in AC circuits only.
As frequency increases, capacitive reactance decreases. This behaviour of capacitor is very useful to build filters to attenuate certain frequencies of signal. Capacitive reactance is also inversely proportional to capacitance. Capacitance and capacitive reactance both changes when multiple capacitors are introduced to the existing circuit.
Unlike resistance which has a fixed value, for example, 100Ω, 1kΩ, 10kΩ etc, (this is because resistance obeys Ohms Law), Capacitive Reactance varies with the applied frequency so any variation in supply frequency will have a big effect on the capacitor’s, “capacitive reactance” value.
Thus capacitance in AC circuits suffer from Capacitive Reactance. Capacitive Reactance in a purely capacitive circuit is the opposition to current flow in AC circuits only. Like resistance, reactance is also measured in Ohm’s but is given the symbol X to distinguish it from a purely resistive value.
