14.2 Magnetic field options

The NSG 3150 is suitable for perform pulsed magnetic field tests as per IEC 61000-4-9. The user is
responsible that the applied surge impulse voltage is in a Range up to 1000 A/m that corresponds to a
surge impulse voltage of approx..2300V.

The user is responsible that the applied surge impulse voltage is in a Range up
to 1000 A/m that corresponds to a surge impulse voltage of approx.2300V.

Pulsed magnetic fields

Tests with pulsed magnetic fields simulate the type of field produced surge pulses such as those
occurring during lightning strokes on buildings and other metallic structures such as free-standing
masts, lightning conductors, earth networks, etc.

NSG 3150 generates these test signals in accordance with the IEC 61000-4-9 standard by inducing a
current (generated by the surge module CWM 3151) into magnetic field loop in which the magnetic
field produced in proportional to the current within the loop parameters.

It is recommended for the user to stay away (at least a few meters) from the loop
antenna while magnetic fields are generated. Also keep away magnetic field
sensitive devices and items such as credit cards

– magnetic key cards etc. which

might be influenced by the field.

Magnetic field loops INA 701, 702 and INA 703

Tests with mains frequency and pulsed magnetic fields are performed using the magnetic field loops
designed for NSG 3150. These are rectangular loops measuring 1 x 1m and are suitable for test
objects with dimensions up to 0.6 x

0.6 x 0.5 m (l x w x h).

Three types of loop can be supplied:

INA 701

The INA 701 is a 1 x 1 m loop

– single turn - with a coil factor of 0.89. It enables the generation of field

strengths of up to 3.6 A / m for mains frequency fields 50 or 60 Hz when used with the MFO 6501 or
MFO 6502 current sources and 1200 A / m for pulsed magnetic fields, where the current is generated
by a 4400 V surge generator.
