Harmonics monitoring survey on office LV appliances

摘要

The paper reports some experimental measurement results concerning current harmonics and power consumptions associated to some single phase non-linear loads supplied in low voltage. In particular some office equipments and florescent lamps have been monitored during their typical operation phases. For the purpose a custom monitoring system has been used. The harmonic monitoring survey has permitted an interesting characterization of harmonic spectrum variability that is very useful for penetration studies based upon a bottom-up approach.
