11. Flicker (EN 61000-3-3)
11.1 Test Procedure
EUT was connected to the Power Analyzer system. Measurements were conducted to obtain the desired
flicker parameters. The measuring time depends on which parameters are to be measured:
◆ 2 hours for Long Time Flicker assessment (Plt)
◆ 10 minutes for Short Time Flicker assessment (Pst)
◆ 1-10 minutes for Dmax, Dc and Dt assessment (depending on EUT switch-rate)
A pure AC mains was supplied to the system from two power supply units. The units supply an AC mains,
free of harmonics, fluctuations or distortion of any kind. A defined impedance was located between the
supply unit and the EUT.
