Elektromágneses összeférhetőség (EMC). 2-4. rész: Környezet. Ipartelepek kisfrekvenciás vezetett zavarainak összeférhetőségi szintjei (IEC 61000-2-4:2002)

Angol cím

Electromagnetic compatibility (EMC). Part 2-4: Environment. Compatibility levels in industrial plants for low-frequency conducted disturbances (IEC 61000-2-4:2002)

Alkalmazási terület

This part of IEC 61000 is concerned with conducted disturbances in the frequency range from 0 kHz to 9 kHz. It gives 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 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 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 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 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. However, 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 choice of immunity levels for the equipment within these systems. The disturbance phenomena considered are: – voltage deviations; – voltage dips and short interruptions; – voltage unbalance; – power-frequency variations; – harmonics up to order 50; – interharmonics up to the 50th harmonic; – voltage components at higher frequencies (above 50th harmonic); – d.c. component; – transient overvoltages.
