In distribution systems, these capacitors provide reactive power to offset inductive loading from devices like motors, arc furnaces and lighting loads. The incorporation of capacitors into a power distribution system offers economical and operational benefits including increasing system load capacity, reducing losses and improving power factor.
In most power applications, inductance prevails and reduces the amount of pay-load power produced by the utility company for a given size of generating equipment. The capacitor counteracts this loss of power and makes powerproduction more economical. Figure 2 – Pole-mounted capacitors.
Inductance is the element in the circuit which is pulling the power factor below 1. Capacitance is the enemy of inductance. Therefore, capacitors counteract inductance, keep the power factor close to 1, and save money for the utility company. The capacitor usually consists of two conductors separated by an insulating substance.
Capacitors are protected with overpressure disconnector, which ensures safe disconnection of the capacitor from the network in the event of overloading or at the end of its operation life. All the capacitors are equipped with built-in discharge resistors. The case of the capacitor is protected against bursting by the overpressure disconnector.
It is the job of capacitors to keep the power factor as close to 1 as possible. The power factor is an important essential of electricity. At this point, let it suffice to say that keeping the power factor close to 1 is a considerable economic advantage to the utility company and to the consumer.
Capacitance is the property of a capacitor. Capacitance depends on the area of the conductors, on the distance between the conductors and on the type of insulating material used. Introducing capacitors into a circuit causes the current to lead the voltage in phase.

PDN frequency response. Placing capacitor further away from load circuit power pins, thus increasing the loop inductance, can lead to ground bounce noise and coupling from power planes to high-speed signal traces. Capacitor placement should be done in such way as to minimize the current path of the inductive loop. [4]
