Harmonic Filters

Harmonic filters enable the reduction of harmonic distortion on electrical power networks.

Enspec Power design and manufacture the VArComp® range of harmonic filters at all voltage levels from 400V up to 500kV to attenuate troublesome harmonics to within defined parameters or dampen system resonances to prevent harmonic amplification.

The detrimental effects of harmonic distortion can be manifested in many ways depending upon various factors such as the level or amplitude of harmonics present on the system and fault level or impedance of the electrical network. Increased heating effects on electrical distribution equipment and conductors caused by harmonics can lead to insulation breakdown and even premature failure of electrical plant. The VArComp® range of harmonic filters can help to prevent such unwanted effects and includes:

• Multi-limb automatic control
• Damped / ‘C’ type filters
• Balanced VAr output
• Real-time / dynamic harmonic filters

Enspec can gather accurate harmonic spectrum information and system details from on-site measurements to provide the basis for accurate VArComp® harmonic filter design using the latest in system-modelling computer software.

We can help you to clean up your electricity supply and ensure the longevity and integrity of your electrical network.
