3.1 interharmonic interharmonics Those in power supply frequency harmonic frequency components between. 3.2 flicker flicker Luminance or spectral distribution caused by time-varying light stimulation unstable visual effects. 3.3 short-term flicker indicator value Pst short-termflickerindicator Evaluation of short-term (a few minutes) within a blink of severities; Pst = 1 indicates the sensitivity of a conventional threshold. 3.4 Long-term flicker indicator value Plt long-termflickerindicator Severities within Pst flicker with a continuous assessment of the value of time (a few hours).

4 Overview

Harmonics and flicker analyzer is mainly used to measure the EUT (equipment under test) injected into the grid at work in harmonic content Volume; changes in its variability and grid voltage EUT caused in the grid frequency.
