IEC 61000-3-11 is concerned with the emission of voltage changes, voltage fluctuations and flicker produced by equipment and impressed on the public low-voltage supply system.
IEC 61000-3-11 specifies the limits of voltage changes produced by equipment tested under specified conditions.
IEC 61000-3-11 is primarily applicable to electrical and electronic equipment having a rated input current from 16 A up to and including 75 A, which is intended to be connected to public low-voltage distribution systems having nominal system voltages of between 220 V and 250 V, line-to-neutral at 50 Hz, and which is subject to conditional connection.
This part of IEC 61000 is also applicable to equipment within the scope of IEC 61000-3-3 that does not meet the limits when tested or evaluated with reference impedance Zref and is therefore subject to conditional connection. Equipment that meets the requirements of IEC 61000-3-3, is excluded from this part of IEC 61000.
Equipment tests made in accordance with IEC 61000-3-11 are type tests.
Advanced Test Equipment Rentals can perform ISO17025 accredited calibration on products that abide by this standard.
NOTE: The flicker limits specified in this part, the same as those in IEC 61000-3-3, are based on the subjective severity of the flicker imposed on the light from 230 V/60 W coiled-coil filament lamps when subjected to 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 are under consideration.
