Specifies the limitation of voltage fluctuations and flicker in low-voltage supply systems for equipment with a rated input current less than or equal to 16 A. This Standard is technically equivalent to and has been reproduced from IEC 61000-3-3:1994.

This section of IEC 1000-3 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods of assessment. This section is applicable to electrical and electronic equipment having an input current up to and including 16 A per phase and intended to be connected to public low-voltage distribution systems of between 220 V and 250 V at 50 Hz line to neutral. The tests according to this section are type tests. Particular test conditions are given in annex A and the test circuit is shown in figure 1.NOTESThe limits in this section are based mainly on the subjective severity of the flicker imposed on the light from 230 V/60 W coiled-coil filament lamps by fluctuations of the supply voltage. For systems with nominal voltages less than 220 V, line to neutral and/or frequency of 60 Hz, the limits and reference circuit values have not yet been considered. Special equipment which is not widely used and is designed in such a way that it is unable to comply with the requirements [limits] of this section may be subject to installation restrictions requiring the consent of the supply authority before connection.A guide to the assessment of such equipment is given in technical report IEC 1000-3-5.
