适用范围

Scope and objectThis part of IEC 61000 is concerned with the emission of voltage changes@ voltage fluctuations and flicker produced by equipment and impressed on the public low-voltage supply system.It specifies the limits of voltage changes produced by equipment tested under specified conditions.This part of IEC 61000 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 which meets the requirements of IEC 61000-3-3@ is excluded from this part of IEC 61000.Equipment tests made in accordance with this part of IEC 61000 are type tests.NOTE The flicker limits specified in this part@ being 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.
