Magnetic field test 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.
The waveform used is defined in Figure 3 of IEC 61000-4-5 (waveform 8/20
μs).
Caution
Only coils with 1 turn
can be used for pulsed magnetic field application.
13.1. Pulsed Magnetic field operation
The menu offers different test routines for pulsed magnetic field testing.
Main menu Pulsed Magnetic Field
The Magnetic Field menu offers different test routines for pulsed magnetic testing.
Quick Start
Easy and fast online-operation with the pulsed magnetic surge phenomenon. In this menu the user can operate
all test manually with online change the most parameters during a test.
Standard
The operator can select between various preprogrammed test routines as required in different standards
The standard library is filtered according the EUT setting (AC, DC etc.)
User test routines
The user defined library where all created magnetic field tests are stored.
