For compensation of reactive power, high-voltage capacitors are used [18, 19 ]. (...) The methods of reactive power compensation in … 67. 2.
Automatic capacitor banks are used for centralized power factor correction at the main and sub distribution boards. Power factor correction means that reactive power charges imposed by electricity utilities can be avoided.
Reactive power compensation is controlled with the N-6 high performance reactive power controller. Power factor correction by means of conventional capacitor banks is not possible in systems affected by harmonics. This is because the harmonic currents are amplified in the parallel resonant circuit formed by the capacitor and the network.
Low (LV) reactive power compensation and harmonic filtering solutions help customers to improve the performance of installations through energy savings and better power quality, enabling end users to save money and reduce the environmental impact of their operations.
GE's DW-series automatic capacitor banks with blocking reactors are intended for power factor correction in systems where harmonic distortion is present. The new modular and compact design saves space and is available with options for wall or floor mounting. The DW-series is available in two variants, standard and extendable.
The low voltage power capacitors comply with most national and international standards. Other voltages up to 1,000 V are available on request. Capacitor elements made of metallised polypropylene film are self-healing and dry without impregnation liquid. Each capacitor element is individually protected with patented internal fuse protection.
