Home Power Quality & Power Factor Correction Active Harmonic Filters

Active Harmonic Filters

Modular & Wallmount Active Power Filters

Most electrical transmission and distribution systems have been designed to operate at the fundamental frequency only and the presence of non-linear loads often stress distribution equipment and can disrupt normal power supply operation.Enersine Active Power Filter measures and monitors the entire load current through external auxiliary coupling current sensing transformers (CT) mounted on the AC line, removes the fundamental frequency component and injects opposite phase harmonic current to cancel harmonic current in the electrical distribution system. By cancelling the harmonics currents in the circuit, there will:

  1. No risk of harmonic resonance
  2. Significantly reduce voltage waveform distortion
  3. Reduced voltages drop and temperature rise on transformer & cables
  4. Improved power factor

Effects of Harmonics

  • Cause transformers derating and/or overheating
  • Reduces overall electrical system power factor e.g. PF0.6 (Energy wastage)
  • Generators unable to switch on or Capacitor Bank burnt
  • Cause Overheating to cables resulting in possible short circuit
  • Interference to communication equipment – resulting in data loss

Why Improve My Harmonics?

  • The harmonic components of order 3 (150 Hz) in three-phase systems become homopolar, for instance: They converge on the neutral conductor and overload it. In the absence of the neutral, circulating currents may occur inside the three-phase appliances, connected in triangular form, generating dangerous overloads in this situation as well.
  • In single-phase systems,  personal computers are classic examples of heavily-distorted loads with a high content of 3rd order harmonics which, as described above, will have an effect on the neutral. The conductor must, therefore, be sized appropriately, otherwise overheating will occur, thus reducing its life and quality.
  • They can cause failure of PLC, DCS, computer, and other sensitive low voltage power supplies.
Harmonic currents can be improved by installing Active Harmonic Filtering (AHF) equipment. To learn more about our Active Harmonic Filters, click on the products above or contact us to receive the best assistance from our Technical Sales Engineers.Customers with Variable Speed Drives The Rural Network Harmonics Standard affects all customers that have connections with a cumulative VSD load exceeding 20kW. The Standard was revised and updated during January 2014. In addition to new installations of Variable Speed Drives (VSD's), effective from 20 January 2014, all existing connections with a cumulative VSD load exceeding 20kW are required to have a harmonic filter installed (or similar mitigation).
