Power Sources and Technology is a well-known company that supplies Power Capacitor. Capacitor is a device that stores energy within an electric field. This is achieved by having two oppositely charged electrical conductors separated by dielectric materials.
Power capacitors are constructed of several smaller capacitors commonly referred to as “elements,” “windings” or “packs.” These elements are formed from multiple layers of aluminum foil (conductors) and polypropylene film (dielectric) wound together. When interconnected, multiple elements combine to function as a single capacitor unit. Elements are connected in series based on rated voltage, and in parallel based on required kvar. The completed module is enclosed in a hermetically sealed tank, and any air from the unit is removed and replaced with a dielectric fluid. Units include bushings with terminal caps, that are used as connection points and to maintain electrical creepage and clearance requirements.
