Active Harmonic Filters

Power quality is a major concern for transmission and distribution utilities, industries, transport and infrastructure sectors. Poor power quality affects grid reliability, productivity, leads to higher operating costs and penalties for non-compliance with grid codes.

Active filters can remedy high harmonics that cause power quality issues including:

  • Failure of conformity with G5/4 and IEEE 519 international guidelines
  • Fuses, switches and sensitive electronic equipment failing prematurely
  • Nuisance tripping, light flickers, overheating of conductors and stresses on transformers

Active filters protect critical industrial, residential and commercial applications, as well as make installations compliant with any prevailing power quality regulations.

Ultimate Answer To Tough Power Quality Problems

Active filters are the ultimate answer to tough power quality problems caused by harmonics, load unbalance and reactive power demand for all applications by all types of customers.

Active filter is a power electronics based equipment that is installed in parallel to the polluting loads. It monitors the line current harmonics and for each harmonic frequency generates a compensation current in perfect phase opposition to the polluting current. It can also perform load balancing and reactive power compensation of loads in a stepless manner. It is an ideal solution for commercial, residential, light, medium and heavy industrial applications, for installations with or without neutral.

Benefits of Installation

There are several benefits of installing active filters:

Operational efficiency

  • Fewer events of equipment failure due to poor power quality of the network, thereby creating more efficient operations
  • Improved performance of loads thanks to a cleaner supply network

Cost efficiency

  • Increased lifetime of the equipment enabling lower plant running costs
  • Compliance with the strictest regulations (such as individual harmonic limits) thanks to the unique control concept, thereby avoiding penalties and/or refusal by utilities to connect installations to the electrical grid

Energy efficiency

  • Lower energy losses in cables and transformers and hence a higher efficiency of the system but also a reduction of CO2 emissions

Better Safety, Better Operation

Better safety of the installations and better operation of sensitive loads as the voltage drop between neutral and earth is reduced
