POLYLUX has developed a series of electromagnetic filters for the elimination of harmonics named ‘Compensators’. These equipments are based on the cancellation and compensation of magnetic fluxes The main advantage of the Compensator is the absence of electronic components and capacitors. The Compensators are therefore maintenance free, have an extremely long lifetime compared with other types of filters and are compatible with any electrical installation HARMONIC PROBLEMS

Phase current Neutral current L1 L2 L3 N Distribution panel HARMONIC PROBLEMS IN OFFICE BUILDINGS UPS Computer equipment in office buildings generate elevated levels of harmonics which cause important problems in the electrical installation The triplen harmonics (3rd, 9th...) are especially harmful as these sum in the neutral conductor and generate a high neutral current causing serious failures and damages in the installation Computer equipment 3rd, 5th, 7th, 9th 3rd, 9th

L1 L2 L3 N Distribution panel UPS Computer equipment 3rd, 5th, 7th, 9th 3rd, 9th HARMONIC PROBLEMS IN OFFICE BUILDINGS There is no phase shift between the 3rd harmonic currents therefore in the neutral you get the sum of all 3rd harmonic currents There is a 120º phase shift between fundamental currents, the sum in the neutral is therefore practically zero in a balanced system Phase Currents Neutral Current Why such a high neutral current? Neutral current can be higher than the phase current. For example, having fundamental 100A and 3rd harmonic 60A in each phase, you will have 180A 3rd harmonic in the neutral The neutral current is the sum of all phase currents L1+L2+L3
