3.7. Power Line Fluctuations/Flicker: EN 61000-3-3 (1995), A1(2001)
EN 61000-3-3 is applicable to household appliances and similar electrical and electronic equipment having an
input current up to and including 16 amps per phase. The objective of this standard is to set limits for voltage
fluctuations of equipment within its scope, and ensures that home appliances and certain other electrical
equipment do not adversely affect lighting equipment when connected to the same utility power line. Large
current variations combined with high utility line power impedance can cause excessive changes in the AC
supply voltage. If these voltage changes are repeated at short intervals, objectionable fluctuations of
luminance (flicker) could be generated in illumination sources connected to the same utility line network.
This test requires an AC power source with a standard impedance network and a power analyzer.
Measurements of steady state and fluctuating harmonics, along with flicker and voltage deviations, are
conducted using a power analyzer, often called a “flickermeter.”
For further information, please refer to the technical sections in the EN 61000-3-3 publication (1995) in
addition to the test results section and photographs of the test set-up provided in this report.
