O
43、thers will be published with the part number followed by a dash and a second number identifying the subdivision (example: 61000-3-11). Detailed information on the various types of disturbances that can be expected on public power supply systems can be found in IEC 61000-2-1 and IEC 61000-2-12. Page4

It giv
45、es numerical compatibility levels for industrial and non-public power distribution systems at nominal voltages up to 35 kV and a nominal frequency of 50 Hz or 60 Hz. Power supply systems on ships, aircraft, offshore platforms and railways are not included. The compatibility levels specified in this
46、standard apply at the in-plant point of coupling. At the power input terminals of equipment receiving its supply from the above systems, the severity levels of the disturbances can, for the most part, be taken to be the same as the levels at the in-plant point of coupling. In some situations this is
47、 not so, particularly in the case of a long feeder dedicated to the supply of a particular load, or in the case of a disturbance generated or amplified within the installation of which the equipment forms a part. Compatibility levels are specified for electromagnetic disturbances of the types which
48、can be expected at any in-plant point of coupling (IPC) within industrial plants or other non-public networks, for guidance in a) limits to be set for disturbance emission into industrial power supply systems (including the planning levels defined in 3.1.5); NOTE 1 A very wide range of conditions is
49、 possible in the electromagnetic environments of industrial and other non-public networks. These are approximated in this standard by the three classes described in Clause 4. How- ever, it is the responsibility of the operator of such a network to take account of the particular electromagnetic and economic conditions, including equipment characteristics, in setting the above-mentioned limits. b) the
