Magnetic field as per IEC 61000-4-9
Pulse magnetic fields are generated by lightning strokes on buildings and other metal structures including aerial
masts, earth conductors and earth networks and by initial fault transients in low, medium and high voltage
electrical systems. In high voltage sub-stations, an impulse magnetic field may also be generated by the
switching of high voltage bus-bars and lines by circuit breakers.
A surge generator as specified in IEC 61000-4-5 is used to generate a short circuit current with the wave shape of
8/20 s. The waveform used is defined in Figure 3 of IEC 61000-4-5.
Only coils with 1 turn
can be used for pulsed magnetic field application.
