IDS has been an ABB inverter partner since 1994 providing complete support and backup to ABB’s market leading products. We are proud to be an ABB VP (Value Provider).
Energy Networks Association Document G5/4-1 2005, details the maximum levels of harmonic distortion that electricity consumers (that includes commercial and industrial users) are permitted to export onto the distribution network. Adding non-linear loads causes quality deterioration. To comply with this legislation a harmonic survey should be conducted and distortions rectified.
We attend your site and monitor for a period of a week, the quality of the mains where it is connected to the rest of the network. From this monitoring we produce an in-depth Harmonic Distortion report – you can see an example of a harmonic survey here as you can see the report also includes an action plan.
Whilst reducing energy consumption inverters can cause harmonic distortion, however there are solutions we can suggest mitigating the effects:
Harmonics can be reduced at source. IDS supply and install low harmonic drives which reduces the harmonics produced to practically zero.
If this is impractical, then we can fit Active Filters. These Filters measure the harmonics on a system and ‘squirt in’ anti-phase currents at the correct harmonic frequency to cancel out the harmonics, working in a similar manner to noise cancelling headphones.
