2010-07-05 - Raise system reliability to unprecedented levels
The High Voltage Products business recently introduced full-redundancy feature in its PQFS range of active filters manufactured in Belgium.
The majority of loads found in electrical installations create harmonic pollution. Examples of such loads include fluorescent and dimmer lighting systems, UPS-systems, converters and drives used in pumps, high speed lifts and cooling systems, computers and other electronic equipment. In addition, certain loads introduce system unbalance or run at a too low inductive or capacitive power factor. All these parameters affect the Power Quality of the system. If the Power Quality deteriorates below a certain level, system reliability is at stake.
ABB PQF active filters are the comprehensive solution for active harmonic filtering, load balancing and reactive power compensation. These features ensure that even the most sensitive loads can run when connected to the supply network. Further, they reduce production and/or commercial system downtime and increase system efficiency. They also allow for installations to comply with even the strictest of Power Quality regulations ensuring that any plant can be connected to the supply.
The PQF active filter range offers ultimate active filtering performance. It also excels through its step-less reactive power compensation ability of both inductive and capacitive loads and through its load balancing features. The ABB PQF active filters offer the best accuracy available thanks to the unique closed loop control systems in combination with the use of different dedicated control loops for the individual harmonic components.
In order to further raise system reliability to unprecedented levels, ABB is proud to announce the introduction of the full-redundancy feature in its range of world class active filters. This feature allows different filter units to work together in a coordinated and efficient manner and permits compliance with even the most stringent requirement on redundancy imposed in critical applications varying from data centers over telecom hubs to sensitive industrial processes.
The full redundancy feature has first been implemented in the wall mounted PQFS range of active filters with individual unit ratings from 30 to 100 Amps being available today. This filter range is mainly used in commercial applications where full redundancy is often requested. Up to 4 PQFS units of the same rating can be connected in parallel.
ABB PQFS active filters with full-redundancy feature are available from now.
