27、ications or technical reports, some of which have already been published as sections. Others will be published with the part number followed by a dash and completed by a second number identifying the subdivision (example: 61000-6-1). Detailed information on the various types of disturbances that can
28、 be expected on public power supply systems can be found in IEC 61000-2-1.

29、ope and object This standard is concerned with conducted disturbances in the frequency range from 0 kHz to 9 kHz, with an extension up to 148,5 kHz specifically for mains signalling systems. It gives compatibility levels for public low voltage a.c. distribution systems having a nominal voltage up to
30、 420 V, single-phase or 690 V, three-phase and a nominal frequency of 50 Hz or 60 Hz. The compatibility levels specified in this standard apply at the point of common coupling. At the power input terminals of equipment receiving its supply from the above systems the severity levels of the disturbanc
31、es can, for the most part, be taken to be the same as the levels at the point of common coupling. In some situations this is not so, particularly in the case of a long line dedicated to the supply of a particular installation, or in the case of a disturbance generated or amplified within the install
32、ation of which the equipment forms a part. Compatibility levels are specified for electromagnetic disturbances of the types which can be expected in public low voltage power supply systems, for guidance in: the limits to be set for disturbance emission into public power supply systems (including the
33、 planning levels defined in 3.1.5). the immunity limits to be set by product committees and others for the equipment exposed to the conducted disturbances present in public power supply systems. The disturbance phenomena considered are: voltage fluctuations and flicker; harmonics up to and including
34、 order 50; inter-harmonics up to the 50 thharmonic; voltage distortions at higher frequencies (above the 50 thharmonic); voltage dips and short supply interruptions; voltage unbalance; transient overvoltages; power frequency variation; d.c. components; mains signalling. Most of these phenomena are d
35、escribed in IEC 61000-2-1. In cases where it is not yet possible to establish compatibility levels, some information is provided.

43、ances to anything in that environment NOTE 1 Electromagnetic compatibility is a condition of the electromagnetic environment such that, for every phenomenon, the disturbance emission level is sufficiently low and immunity levels are sufficiently high so that all devices, equipment and systems operat
44、e as intended. NOTE 2 Electromagnetic compatibility is achieved only if emission and immunity levels are controlled such that the immunity levels of the devices equipment and systems at any location are not exceeded by the disturbance level at that location resulting from the cumulative emissions of
45、 all sources and other factors such as circuit impedances. Conventionally, compatibility is said to exist if the probability of the departure from intended performance is sufficiently low. See 61000-2-1 clause 4. NOTE 3 Where the context requires it, compatibility may be understood to refer to a sin
46、gle disturbance or class of disturbances. NOTE 4 Electromagnetic compatibility is a term used also to describe the field of study of the adverse electromagnetic effects which devices, equipment and systems undergo from each other or from electromagnetic phenomena. IEV 161-01-07, modified 3.1.4 (elec
47、tromagnetic) compatibility level the specified electromagnetic disturbance level used as a reference level in a specified environment for co-ordination in the setting of emission and immunity limits NOTE By convention, the compatibility level is chosen so that there is only a small probability that
48、it will be exceeded by the actual disturbance level. IEV 161-03-10, modified 3.1.5 planning level a level of a particular disturbance in a particular environment, adopted as a reference value for the limits to be set for the emissions from large loads and installations, in order to co-ordinate those
49、 limits with all the limits adopted for equipment intended to be connected to the power supply system NOTE The planning level is locally specific, and is adopted by those responsible for planning and operating the power supply network in the relevant area.
