36、to the immunity requirements of equipment, only under operational conditions, to pulse magnetic disturbances mainly related to: - industrial installations and power plants; - medium voltage and high voltage substations. The applicability of this standard to equipment installed in different locations
37、 is determined by the presence of the phenomenon, as specified in clause 3. This standard does not consider disturbances due to capacitive or inductive coupling in cables or other parts of the field installation. Other IEC standards dealing with conducted disturbances cover these aspects. The object
38、 of this standard is to establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment for household, commercial and industrial applications when subjected to pulse magnetic fields. The standard defines: - recommended test levels; - test equipment; -t

42、eration of equipment and systems. The following tests are intended to demonstrate the immunity of equipment when subjected to impulse magnetic fields related to the specific location and installation condition of the equipment (e.g. proximity of equipment to the disturbance source). Pulse magnetic f
43、ields are generated by lightning strikes on buildings and other metal structures including aerial masts, earth conductors and earth networks and by initial faults transients in L.V., M.V. and H.V. electrical systems. In H.V. substations, a pulse magnetic field may also be generated by the switching
44、of H.V. bus-bars and lines by circuit breakers. The test is mainly applicable to electronic equipment to be installed in electrical plants as well as in telecontrol centres. It is not relevant for distribution network equipment. Possible other applications may be considered by the product committees
45、. The test field waveform is that of the standard current pulse, waveform 6,4/16 p. NOTE The waveform 6,4/16 ps according to IEC 469-1 corresponds to the 8/20 ps of IEC 60-2.
