Specification of AHF electrical panel 30-300 A Active Harmonic Filter
Description:
Industrial and Commercial applications are making increasing use of large numbers of PCs, Servers, UPSs, AC / DC drives, Rectifiers, Chargers, SMPS, Energy saving CFL lamps, etc. These sorts of equipment draw current which is non-sinusoidal in nature, which categories them as non-linear types of load.
These non-linear loads put extensive stress on electrical distribution systems as a result of the generation of harmonic currents.
The high level of harmonics lowers power factor, affects the power usage and reduces component life. They also affect performance of DG sets & utility transformers, cables and switchgears used and cause great drains on the power supply.
The harmonic pollution can be effectively controlled by making use of Active Harmonics filter. These are solid state designs which measure level of current harmonics in the supply line and eliminate them by generating counter harmonics. The control and reduction of harmonics improves the power
quality and makes the electrical distribution system more efficient. Power savings of 10% to 30% are possible, depending on the application.
Chloride Swan+ is a state-of-the-art Active Harmonics filter, which improves the power quality in the electrical supply. It increases the reliability of the installation and gives better control over the power flowing in the electrical system. This boosts the profitability for supply authorities as well as the end user.
