Harmonics & Flicker Rental Equipment

Description

Overview

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 the luminance or the spectral distribution of lighting systems. The impression of the unsteadiness of visual sensation induced by this light stimulus is called flicker. The DPA500N harmonics and flicker analyzer is used for single phase applications.
