We define the reactive power to be positive when it is absorbed (as in a lagging power factor circuit).. a. Pure capacitance element – For a pure capacitance element, P=0 and I leads V by 90° so that complex power is:. S = jQ = (V ∠0°) (I ∠90°) S = V×I ∠−90° S = −jV×I. Thus the capacitance element generates reactive power.
3.2 Step capacitor banks with automatic regulation. This type of device enables the reactive power supplied to be adapted to variations in consumption, thus keeping the compensation at its optimum value. It is used in situations where the reactive power consumption varies considerably and is high in relation to the power of the transformer.

The true benefit is when an inductor AND a capacitor are in the circuit. Leading capacitive reactive power is opposite in polarity to lagging inductive reactive power. The capacitor supplies power to the inductor decreasing the reactive power the source has to provide. The basis for power factor correction. Select RLC in the reference.

A shunt capacitor is extensively used to transmit reactive power to loads in the main distribution. These capacitors supply an economical reactive power to meet up reactive power necessities for different loads. The transmission, as well as distribution lines, operates at lagging PF (power factor) to reduce line losses & enhance voltage regulation.
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.

As a consequence, a full load reactive power compensation may lead the system to fail prematurely and make this ancillary service economically unfeasible. Therefore, if a desired lifetime is targeted, there is a maximum reactive power specification which the PV inverter can compensate without compromising its lifetime.
5. Discharge resistor: All Capacitors provided with discharge resistors to discharge the capacitors to voltage less than 50V within 1 minute. For the extreme safety of operator it is advice to discharge capacitor before handling. Caution: Power capacitors are highly susceptible to pre mature failures if capacitors selected wrongly.

The results achieved are as follows: • Without a shunt capacitor, apparent power carried by the line SL = PL + jQL, and power factor cosϕ = PL /SL • With a capacitor, line apparent power, SL1 = PL + j(QL – QC) < SL, and cosϕ1 = PL / SL1 > cosϕ • Ultimately, power losses ∆P and voltage drop ∆V will be reduced after shunt capacitor is installed, i.e. ∆P1 < ∆P, and ∆V1 < ∆V

As with the simple inductor circuit, the 90-degree phase shift between voltage and current results in a power wave that alternates equally between positive and negative. This means that a capacitor does not dissipate power as it reacts against changes in voltage; it merely absorbs and releases power, alternately. A Capacitor''s Reactance
