INA 703 Magnetic field coil
2.3 Pulsed magnetic field
The Teseq ProfLine system comprising an NSG 1007- 5 kVA source, an INA 2141
impedance box and WIN 2120 software is ideally suited for this application. For this
setup the interconnection cable INA 3250 is required.
The system can generate supply frequency fields (50 and 60 Hz) up to 330 A/m
continuously and 1100 A/m short term (3 s).
For more information please consult ProflLne 2100 series user documentation.
The INA 703 can also be used with the Teseq MFO 6501 or 6502 current sources
and the NSG 3000 series of generators to generate supply frequency fields (50 and
60 Hz) up to 120 A/m continuously and 120 A/m short term (3 s). For this setup the
interconnection cable INA 3251 is required.
For more information please consult MFO 6501/2 or NSG 3040 series user manuals.
Pulsed magnetic fields tests, simulate the type of interference produced by surge
pulses as a result of lightning strikes to buildings or other metallic structures such
as free standing masts, ground conductors, grounding networks, etc. as specified
in IEC/EN 61000-4-9. Magnetic fields of this type can upset the operation of instal-
lations that find themselves within such fields.
For testing to IEC 61000-4-9, the INA 703 can be used together with a classic com-
bination wave generator such as the NSG 3040 or NSG 3060 series.
For this test a single loop ( 1 turn) will be used.
In order to meet the pulse waveform required by IEC 61000-4-9, the waveshape
adapter INA 752 needs to be used.
