>> do you have power quality issues on your network?
You may have experienced one of the following: frequent failure of equipment, reduced life of equipment, production losses, reduced safety levels of installations, increased carbon footprint or non- compliance with utility regulations.
There are 3 significant sources of poor power quality caused by a variety of loads in customer installations.
High voltage distortion can result in equipment failure, production time and costly repairs to the electrical distribution network. If power factor correction capacitors are installed on the system parallel resonance can occur amplifying harmonics currents and the adverse effects on the network.
>> what are harmonics?
Harmonics refer to the voltage and current harmonic distortion within an AC circuit. These harmonic currents may result in distortion of the supply voltage waveform and can adversely affect other equipment connected to the network by causing overloads or EMC interference.
>> where do they come from?
All non-linear loads create harmonics. A load which draws a non-sinusoidal (distorted) current, when a pure sinusoidal voltage is applied, is a non-linear load.
Typical sources of harmonics:
The diagram shows an electrical waveform with harmonic distortion.
The PQF active filter range is suitable for small or large applications (30 A - 3600 A) and do not get affected by changes in network impedance (transformer paralleling, switch to backup generator), providing perfect filtering results.
