The reactive power of the capacitor is a function of its rated voltage and current. Three-phase PFC applications have two types of capacitor connections: star and delta. From the formula if we find the with ratio: C will be constant. Example 1: The relationship between active, reactive and real power and cos φ.
Capacitors are used to supply reactive energy to inductive loads. Reactive energy must be produced as closely as possible to the loads to prevent unnecessary flow of current in the network. This is known as power factor correction. [VAr] The reactive power of the capacitor is a function of its rated voltage and current.
Power factor correction (PFC) capacitors produce the necessary leading reactive power to compensate the lagging reactive power. They should be capable of withstanding high inrush currents caused by switching operations (>100 · IR).
In the diagram below, the power triangle shows an initial power factor of 0.70 for a 100 kW (real power) inductive load. The reactive power re-quired by the load is 100 kvar. By in-stalling a 67-kvar capacitor, the apparent power is reduced from 142 to 105 kvar, resulting in a 26% reduction in current. The power factor is improved to 0.95.
Determine the necessary effective power (KVAr) of the capacitor bank in order to obtain the desired PF. Design the capacitor stages in such a way that the sensitivity of the bank is around 15–20% of the total available power.
The power factor of a load is defined as the ratio of active power to apparent power, i.e. kW: kVA and is referred to as cosf. The closer cosf is to unity, the less reactive power is drawn from the supply: Power Factor (cosf) = in/out 4/6/8/12 steps of capacitor banks as the power factor Apparent power(KVA) varies.

Reactive power compensation: a basic overview
Instead of using capacitor banks, there is a different alternative to compensate the reactive power that is based on the use of synchronous compensators. These are synchronous machines that, operating with null active power, can behave either as variable capacitors or coils, by simply changing their excitation current [1].
