ABSTRACT
Capacitor element: an indivisible part of a capacitor consisting of electrodes separated by a dielectric material
Capacitor unit: an assembly of one or more capacitor elements in a single container with terminals brought out
Capacitor segment: a single-phase group of capacitor units with protection and control system
Capacitor module: a three-phase group of capacitor segments
Capacitor bank: a total assembly of capacitor modules electrically connected to each other
At a casual look, a capacitor seems to be a very simple and unsophisticated apparatus, that is, two metal plates separated by a dielectric insulating material. It has no moving parts but instead functions by being acted upon by electric stress.
