LV Power Factor Correction

Electric capacitors are one of the cheapest and simple sources of energy saving currently known, which allow both the distributor and the company to save money. Power factor correction determines a rational use of electric power, reducing the undesired effects of load currents such as motors, transformers, etc., and losses due to the Joule effect in the cables and devices (switches, transformers) present on the energy transport system. Moreover, the additional costs that would be incurred, without PFC, are so high that they result in a very rapid return on investment.
 

Automatic Power Factor Correction equipment

Automatic power factor correction equipment are the most complete and intelligent solution – thanks to the management of the regulator – to compensate for reactive energy. Through an excellent division of the steps, the power of the capacitor banks allow producing the most accurate quantity of reactive power, thus guaranteeing the highest achievable power factor (cosphi). Automatic PFC systems differ on the basis of one or more of the following criteria:
- Rated voltage and frequency
- Maximum voltage allowed on capacitors

When in the presence of harmonics, it is necessary to choose systems equipped with blocking reactors, which differ according to:
- Maximum total harmonic distortion rate in current (THDi Max.)
- Maximum total harmonic distortion rate in voltage (THDu Max.)

Furthermore, all the series can be designed with static insertion: the technology involves the insertion of each capacitor bank by means of zero-crossing static relays (thyristors), instead of traditional electromechanical contactors. This type of insertion is necessary for all those applications that require very high electrical duration and/or operating frequency, high resistance to shocks, vibrations, and movements (e.g. overhead cranes), or in installations where it is necessary to use silent equipment (e.g. offices, banks, homes, hotels, …).
