Power capacitors are important components in systems for transmission and distribution of electric power. Power capacitors are used primarily to increase power transmission capability through parallel and series compensation, for voltage stabilisation through static var-systems, and as filters for eliminating harmonics. A capacitor installation for relatively high power applications generally comprises within a single enclosure a plurality of capacitor sections that are mutually interconnected in parallel and/or series combination to achieve the desired capacitance. A low-voltage electrical power capacitor is generally made up from capacitive windings formed by a coil of metallized dielectric films. High power capacitors are generally used without any special protection, an external coating of enamel or varnish being sufficient to ensure completely satisfactory operation under normal conditions of use.
