Power Factor Correction and Harmonic Filtering
MORE THAN JUST A SIMPLE PROBLEM
In recent years, substantial growth in the number of electronic devices designed to equip our installations has resulted in significant changes in the types of loads connected to the power distribution system.
These devices are currently equipped with electronics that in one way or another increase the efficiency of the tasks, production processes and activities we perform. Everyone uses computers for personal use or for processing and
controlling production systems with speed drives, air-conditioning units, lifts that slow down when approaching their destination floor, etc. These devices are equipped with rectifiers, modulators, etc., which distort the wave shape of the current to achieve their correct operation.
All in all, these devices and units have definitely improved our quality of life; however, they also lead to greater contamination of our electric system and thus to high levels of harmonics.
Ideal wave shape and distorted wave shape
How are harmonics generated?Harmonics are produced by non-linear loads that absorb non-sinusoidal current. The most common loads, in both industrial and domestic environments, are the following:
—Speed / frequency drives —Discharge lamps (mercury vapour, sodium, energy-saving, etc.) —Rectifiers —AC/DC transducers —Arc welding —Induction furnaces —UPS —Computers
What anomalies do they generate?
—Errors in electronic units —Heating of conductors —Neutral overloading —Circuit breaker tripping —Capacitor overloading —Transformer vibrations —Heating of transformers —Heating of motors

MORE THAN JUST A SIMPLE PROBLEM A SINGLE SOLUTION
The range of AFQ active parallel multi-function filters offers the most complete solution for solving quality-related problems in industrial, commercial or service installations, caused not only by harmonics but also by current offsets (depending on the model) and even by the consumption of reactive power (usually of the capacitive type).AFQ filters are equipped with an intuitive touch-screen display, allowing all the necessary programming actions to be performed.

Harmonics without AFQ
They also display the network status upstream and downstream from the filter connection point, providing a "before and after" comparison which can be used to assess the effectiveness of the filter. If greater filtering capacity is required, up to eight filters can be connected in parallel (the same model of filters should be used). AFQ active filters are multi-function 3-in-1 units, with cutting edge technology to perform three different functions with a single unit:
1. Harmonic filtering 2. Power factor correction 3. Phase balancing
Reduction of harmonic currents up to
the 50th harmonic (2,500 Hz). Optional
selection of the harmonic frequencies
to be filtered in order to achieve higher
efficiency.
Power factor correction. Both inductive
and capacitive currents.
Current balancing correction, improving
the phase-to-phase consumption of an
installation. The 4-wire model reduces
the neutral current.

VERSATILE
Start-upEasy to install and use
Touch-screen display
AFQ filters feature an advanced system that enable quick start-up with three simple steps:
AFQ filters have been designed for easy installation and management, offering top performance from day one. The following functions greatly improve the start-up process:
» Three-step start-up: Connect, Configure, Start.
» Touch-screen display for quick management of all parameters: quick, self-explanatory menus.
» Alarms: polarity, temperatures, resonance, voltages, overload, contactors, etc.
Touch-screen HMI display, for quickmanagement and configuration of the unit.
It can also displaythe "in situ" filter data.
ConnectivityCheck the data of your active filters in real time, process the data via the screens and generate reports by remote connection using PowerStudio SCADA.

AFQ active filters are very versatile, since they can be configured with different configurations and operating modes. Therefore, they can be used in any type of installation and for any type of situation:
» vailable for 3- or 4-wire installations. » Available voltages: 230, 400 and 480 V (AFQ-3W). » They adapt to the complexity of each installation,
since they are connected to the load or network side » Adjustable priority to power factor correction,
phase balancing and harmonic filtering
Expandable
Multi-function
The installation can be expanded with up to eight active filters in parallel, which can have different nominal values.
AFQ active filters can work in 12 different modes, with a series of simple combinations, prioritising their three main functions: Harmonic filtering, Power factor correction and Phase balancing.

Standard installation Active filtering units should be installed on the main line (Level 2), according to the filtering needs, for example in an electric vehicle charging station or an industrial
unit with various sources of harmonics; or else they should be installed close to the loads (Level 3), such as in the case of a Data Processing Centre (DPC).
