Electrolytic capacitors consist of two or more conductive capacitors plate, separated by a dielectric. When an electric current enters the capacitor, the dielectric stops the flow and a charge builds up and is stored in an electric field between the metallic plates. Each capacitor is designed to have a particular capacitance (energy storage

Most common low voltage problems in distribution systems can be addressed by installing capacitors. But, how to optimally place and size the capacitors? And how would the capacitors impact the system due to harmonics and switching transients? In this article, we propose to address these questions.
Placement of capacitors in Distribution system. The location of low voltage capacitors in Distribution System effect on the mode of compensation, which may be global (one location for the entire installation), by sectors (section-by-section), at load level, or some combination of the last two.
Capacitors are installed at various points on distribution systems and in certain customer facilities to help increase power factor, which is the ratio of real power (kWh) to apparent power (kVA).

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.
