Power Quality products act as electrical filters by removing or reducing the level of harmful harmonics and re-shaping the sinewave for the longevity of operation of electrical systems. RFI filters reduce the level of conducted RFI and EMC Shielding products reduce the effects of radiated RFI.

Harmonics are very harmful within an electrical system and can have serious consequences. The presence of harmonics reduces the life of equipment and creates heat, which stresses cables and equipment. It is possible that the investment that you made in your motors & drives will not be realised if they are damaged and need replacing before their expected life span. The presence of harmonics will also mean that although you will get billed for the power that you are supplied, a large percentage of that power may be unusable. Harmonic mitigation is taking action to minimise the presence of harmonics in your electrical system and can achieve great cost savings.

Variable Speed Drives (VSD’s) are prolific creators of harmonics in electrical systems and as a result, most of the harmonic mitigation effort focuses on the input side and output side of a VSD. For the mitigation of harmonics on the input side (line side) of a VSD we recommend Line Reactors, Passive Harmonic Filters and Active Harmonic Filters. For the mitigation of harmonics on the output side (load side) of a VSD we recommend Load Reactors, dV/dT Filters and Sinewave Filters.
