AB Lifasa capacitors are manufactured using the most advanced technology and is achieved from an indepth knowledge of the manufacturing process and also from very strict laboratory and Research & Developments tests.

AB Lifasa Automatic capacitor/Filter banks are used for centralised compensation of power factor in low voltage installations.

AB Lifasa also provides wide range of automatic capacitor banks with harmonic filters. These equipments are supplied completely assembled and are ready for use. It is only necessary to connect it to the mains with cable of adequate cross section, and to supply the operation signal from a suitable current transformer.

Compensation is recommended for the power systems like capacitor bank, automatic capacitor bank, used for energy distribution or to feed H.V machines, where consumer could avail return on investment within a shorter period. High voltage power capacitors are meant for power systems where network voltage is more than 1 kV.

High voltage capacitor banks are mainly installed in the following type of applications:

• Cement factories.
  
• Electric arc furnace installations.
  
• Chemical and petro-chemical plants.
  
• Water pumping stations.
  
• H.V motor centers.
  
• Water purification plant.
  
• Desalination plants.
  
• Wind farms.
  
• Airports.
  
• Power generating stations and mini power generating stations.
  
• Transmission centers / Sub – stations.
  
• Paper manufacturing units.
  
• Electric power distribution companies.
  
• Large industries in general.

Capacitor that appears in this chapter are specially designed for applications where there are some necessary capacities with many power electronics components like
Switching circuits, absorption circuits, low voltage special filters, continuous input systems, electronic capacitor, industrial power capacitor, etc. In general any application that needs a high stability of capacity on time and/or high connection currents.

Power Transmission and distribution networks are designed to operate with sinusoidal voltage and current having constant frequency. However there are number of non -linear loads, such as thyristor drives and converters, that generate harmonics on the network, causing distortion in the voltage and current waveforms. These filters are used when the main objective is not the reactive power compensation at the fundamental frequency, but to reduce the harmonic distortion in the supply system.

Reactive power controllers MCE and MCX are designed to measure the reactive power of an installation and to give the necessary instructions for connecting & disconnecting capacitors in order to maintain the desired cos Ö.

All the controllers are commanded by a microprocessor that ensures an uniform ageing of contractors and capacitors by using a circular connection sequence that takes into account the time that each capacitor has been switched on.

Power factor value to be reached can be adjusted in a continuous way, between 0.85 inductive and 0.95 capacitive.

Standard working programs for controllers are 1:1:1:1, 1:2:2:2, 1:2:4:4, 1:2:4:8 and 1:1:2:2.
