28、 techniques Part 5: Installation and mitigation guidelines Installation guidelines Mitigation methods and devices Part 9: Miscellaneous Each part is further subdivided into several parts published either as International Standards or technical reports, some of which have already been published as se

29、ctions. Others will be published with the part number followed by a dash and a second number identifying the subdivision (example: 61000-3-1 1). The scope of this part overlaps with that of IEC 61000-3-3 in that it is also applicable to equipment with a rated input current 516 A. However, it should

30、be noted that equipment having a rated input current 516 A should first be tested for conformity with IEC 61000-3-3 before applying the evaluation techniques and measurement procedures specified in this part of IEC 61000. Equipment which meets the requirements of IEC 61000-3-3 is not subject to cond

31、itional connection and therefore it is not subject to this part of IEC 61000. The limits in this part relate to the voltage changes experienced by consumers connected at the interface between the public supply low-voltage network and the equipment users installation. Therefore, it cannot be guarante

32、ed that the user of equipment compliant with this standard will not experience supply disturbance within his own installation, as the impedance at the point of connection of the equipment to the supply within the installation may have an impedance greater than the test impedance. o BSI 01-2001 Page

34、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

35、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

36、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

37、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

38、 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 andlor frequency of 60 Hz. the limits and reference circuit values are under consideration. 2 Normative references The following normat

For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However parties to agreements based on this part of IEC 61000 are encourag
