Electromagnetic compatibility (EMC) Part 3-3: limits - limitation of voltage changes,voltage fluctuations and flicker in public low- voltage supply systems, for equipment with rated current < 16 a per phase and not subject to conditional connection
This standard 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 standard is applicable to electrical and electronic equipment having an input current equal to or less than 16 A per phase, intended to be connected to public low-voltage distribution systems of between 220 V and 250 V line to neutral at 50 Hz, and not subject to conditional connection.
