DPA 503N - Full-compliant 3-phase harmonics and flicker analyzer Harmonics and interharmonics are caused by modern electronic power conditioning modules. Such, mostly non-linear, modules to control loads and to reduce power consumption is the source of voltage at unwanted frequencies superposed on the supply voltage. Voltage fluctuations caused by varying load currents may influence luminance or spectral distribution of lighting systems. The impression of unsteadies of visual sensation induced by this light stimulus is called flicker. The DPA 503N is used for 3-phase applications but also supports single phase applications.
