Special high-voltage and impulse capacitors

Static Capacitor Banks are widely used in AC electricity transmission lines (ETL) which are switched on either in-parallel (shunt) or in-series into a break of ETL (series), and serve to increase transmitted power along ETL and to increase a stability of power energy system operation. Special capacitors and capacitor blocks are used to complete static capacitor banks.
At electrical energy transmission along DC ETL the capacitors take a big specific weight in the equipment (about 30% of ETL total cost), which are used as damping and equating elements in converting devices and also to complete filter and shunt banks at accepting and sending ends of line.
Over the last years power semi-conductive (thyristor) converting devices for electric drive control are widely used which replace a contact-rheostatic control. One of the most important elements of these devices are capacitors meant for reactive power compensation, higher harmonics filtration and oscillations damping. Application:

*for operation in banks of inductive furnaces and other AC electrothermal plants 50 Hz;
** for power factor correction for shunt and filter banks of DC ETL;
*** for operation in plants of longitudinal compensation of ETL reactive resistance;
**** for operation in shaping lines of impulse devices and other impulse plants;
for operation in circuits of AC auxiliary machines of electric locomotives.
* for damping vibrations.

1) Impulse capacitors are used in the plants for high-voltage impulse tests of power transformers, apparatuses, cables and external insulation of electricity transmission lines (impulse voltage generators, switching surge generators, impulse current generators), designed for operation in various impulse circuits and plants/banks.
2) DC capacitors are used to reduce harmonic currents passing through DC lines for operation in DC thyristor impulse converters, for operation in the circuits of high-frequency filters of traction substations.
