Epcos active harmonic filters and power optimizers help to eliminate harmonic pollution from the grid, reduce power quality problems and use energy more efficiently and reliably. Harmonic pollution is a growing problem with the increasing use of power electronics and non-linear loads (such as variable speed drives, UPS, computers, servers, TV sets, etc.).
AHF PQSine S series monitors the current signal and compensates the unwanted elements of the measured current of the measured current. Thus, the filter ensures harmonic suppression independently on the number of loads. It also corrects the power factor, improving the system efficiency while reducing harmonic pollution. The presence of harmonics increases the RMS current in power networks. The circulation of harmonic currents through the system impedance creates voltage harmonics which produce voltage distortions and thus deteriorate the quality of the supply voltage. This leads to higher operating and energy costs, production/process downtimes, over-heating, and malfunction of equipment.
