How Capacitor Banks Work
A capacitor bank combines the strength of various capacitors to improve the storage capacity of an electrical system. The capacitor consists of two conductive plates, either made of aluminum or tantalum. These plates are separated by a dielectric material such as ceramic, glass, or treated paper. The main function of a capacitor is to store electrical energy between the plates in the electrostatic field.
The capacitance, or the amount of charge a plate can store, will depend on various factors, including the surface area of the plates, the distance between the plates, and the properties of the dielectric material.
When a capacitor is connected to a power source, electrons are collected on the plate that is connected to the negative terminal, and this creates a dense electrostatic field. Once the electrostatic field is created, the capacitors will retain their charge even if they are disconnected from the source of energy, making them a temporary energy reservoir.
The operation of a capacitor bank revolves around reactive power compensation and power factor correction. The primary function is to manage the reactive power in electrical systems, which is essential for maintaining voltage levels and ensuring efficient power delivery.
Reactive power is the power that oscillates between the source and load, primarily due to inductive loads like motors and transformers. Capacitor banks provide leading reactive power, effectively canceling out the lagging reactive power, thereby improving the overall power factor of the system.
