Capacitor: A Short History »

In October 1745, Ewald Georg von Kleist of Pomerania invented the first recorded capacitor: a glass jar coated inside and out with metal. The inner coating was connected to a rod that passed through the lid and ended in a metal sphere. By having this thin layer of glass insulation (a dielectric) between two large, […]

Capacitor: Stored Energy »

A capacitor is an electrical device that can store energy in the electric field between a pair of closely spaced conductors (called ‘plates’). When current is applied to the capacitor, electric charges of equal magnitude, but opposite polarity, build up on each plate.
Capacitors are used in electrical circuits as energy-storage devices. They can also be […]

Capacitor Sizing »

Kvar has patented an apparatus and methodology for determining to an exact science, the amount of capacitance that is needed to optimize inductive motors to unity.
Electric AC motors use more then half of all electricity.
Most AC induction motor operates at 80% efficiency under a full load … the efficiency drops dramatically at lower loads.
NASA research […]
