Active Harmonic Filter 

 

Optimize your harmonic filtering efficiency: the 3-Level Topology Design Approach

  

Active harmonic filters are based on power electronic technology, designed for mitigating harmonics injected by non-linear loads in power networks. Generally installed in parallel to the polluting loads, the active filters analyze the line current harmonics drawn by the loads and generates a compensation current at the opposite phase angle, thereby “neutralizing” the harmonic currents.

 

 Incorporating the 3-level topology design, Sinexcel active harmonic filters (AHF series) are the ideal, comprehensive solution, offering an optimal harmonic filtering efficiency, load balancing and reactive power compensation for applications of all types. Its compact high performance is testified by a track record of more than 120,000A installations.

 

 Key features

 

The Sinexcel Modular Active Harmonic Filter series are suitable for applications of all types, providing harmonic mitigation, load balancing and step-less reactive power compensation for inductive and capacitor loads.  

 

Optimized harmonics filtering efficiency

 

Selection of every harmonic to the 50th order /Filter up to 50 harmonics  simultaneously /Harmonic filtering levels [%] can be pre-configured for each harmonic order in specific/Resonance protection by means of pre-configuring harmonic filtering levels for the potential resonance zones/Harmonic attenuation > 97%

 

Compact high performance

 

Ultra-compact, space economical/User-friendly, ease of commissioning/Parallel capability of modular AHF units with respect to network requirements/Available in rack, wall mounting designs and complete enclosure type 

  

Enhanced Reliability Levels

 

Incorporates intelligent FFT calculation method 

Provides “real time sensing” of network impedance for progressive harmonics compensation to achieving system stability/ Advanced control algorithm for resonance protection/ In event of parallel resonance with load variations, the AHF is designed to assess and “shut-down” to avoid equipment damage 

 

Provide wide ranging protection modes:

Internal temperature diagnostic function to avoid overheating of internal components /internal short circuit /Overload protection/ CT reverse polarity and wrong configuration of CT settings

 

Segregated cooling design

Internal component groups are partitioned in 2 parts, i.e. circuit boards and heat producing elements. The former group will be of natural cooling and dust-protected whereas the latter group will include ventilation fan for effective heat dissipation.
