For application of magnetic fields higher than 600A/m using
a motor variac NX1 or VAR 3005A-S16, a mains voltage of
230V is necessary. Mains with 115V needs an external
booster transformer 115V to 230V 10kVA.
If the MFT100 is delivered to an existing previous model
MS100, two additional plugs are delivered for connect to
MS100.

Generators
The most comfortable test equipment to conduct magnetic field tests as per IEC 61000-4-8 and IEC 61000-4-9 is
the compact generator type compact NX5 / compact NX7, NSG 3040A, NSG 3060A series.
For easy testing 50Hz / 60Hz magnetic field an ac source like NetWave is very comfortable.
- Maximum control comfort.
The most powerful control capabilities are included in the compact NX and NSG 30x0A series generators Within
these units the magnetic field test is integrated in the device app software as well as in the user friendly
iec.control windows software.
- Alternatives
Magnetic field tests can also be conducted together with a VCS 500N surge generator (IEC 61000-4-5) and
PFS 500N series generator (IEC 61000-4-11). It is necessary to modify the DIPS or surge routines for perform
these tests.
Pulsed magnetic field
The pulsed magnetic field as per IEC 61000-4-9 will be realized by using a surge generator as per IEC 61000-
4-5. Some older generators require an additional 18 uF capacitor, that is in series with the coil antenna. Newer
surge generators have already a built in 18 uF capacitor

1.2.
Magnetic field antenna
The correction factor of the magnetic field antenna type MFC 1000 series is 0.87. This means that an antenna
current of 100 A will generate a magnetic field of 87 A/m in the center of the antenna (1m x 1m Antenna). To
achieve 100 A/m an antenna current of 114.94 A is necessary.
This factor is also an important value which shall be entered to the software. Depending on the dimension and the
design of the antenna this factor will change.
Magnetic field antenna MFC 1000.1
Plugs for connect MFC 1000.x
The magnetic field antenna has two different types of connectors.
- Two sets of parallel safety banana connectors for the range of 30 A/m and an optional set of connectors
for higher currents.
- The high current 14mm connectors are used with the MFT 100 only. The cables are part of the transformer.

Cable to the magnetic field antenna
According to the standard the cable between the magnetic field generator (Transformer) and Antenna should be
-Twisted
- Max. 2 m as per IEC 61000-4-8
-Max. 3 m as per IEC 61000-4-9
The delivered 2.5 mm2cables have a length of 2 m 5% and must be prepared for the magnetic field test.
The user must twist or weave the four wires to a cable that has a total length of less than 2.0 m
This arrangement with a twisted cable has the following advantages:
-the cable radiates less, because the field is compensated
-The inductance of the cable loop is less
-Better handling because only one cable is there for the setup

Current transformers
General setup for magnetic field
Two different current transformers are available:
- MFT 30 to generate continuous magnetic fields up to 30
A/m
- MFT 100 to generate continuous magnetic fields from 80
up to 100 A/m and short time magnetic fields up to 1000
A/m.
The transformers can be interchanged depending in which
range the operator has to test.
Please use always the attached original connection cables.
Your system was calibrated together with these cables and
the equivalent transformation factors are part of the software.
MFT 30 MFT 100
Using other components, the test setup shall be recalibrated and the equivalent factors shall be entered to the
software. Changing the test setup will require also a change of the factors (see para. 5.0 verification).
Magnetic field testing needs 230 V mains voltage for user with motor variac (variac NX1-260-16 / VAR 3005A-S16).
An external booster transformator (115 V to 230 V 10 kVA) is necessary for 115 V mains.
Transformer factor F
The given transformer factor is valid for short test up to one minute. For longer tests this factor will change, till the
system is in a stable temperature balance (10-20 minutes). Special higher currents are heating up the cables and
antenna. Therefore, the ohmic value of the cables and antenna increases during the test. The reason is the
heating caused by the high current. For longer application it can be necessary to readjust the voltage when the
temperature of the cable and antenna is stable.
1.4.1.
Measure the transformer and current factor
The test setup can be checked at the following measuring points.
Measuring points for H-field
verification
For verification the magnetic field please uses the following testpoints:
V1 Primary voltage magnetic field transformator
A2 Current in the antenna Loop (measured with a current transformer).
H1 H-field (measured with a H-field sensor).
Other measuring points, as shown in the figure above can be used for H-field measurements.

Current transformer MFT 30
The MFT 30 has two current ranges 3 A and 30 A. The ranges can be select with the switch
at the rear side of the MFT 30. The two parallel current outputs to the antenna can be used
with connectors for 4 mm or 50 A.
The V/I characteristic of the transformer determines the voltage at the output of the variac to
generate the specified magnetic field. because the magnetic field antenna has a very small
impedance the impedance of the wiring mostly determines the V/I characteristic of the current
transformer.

Current transformers MFT 100-120/230
The MFT 100 is used for high magnetic fields from 80 A/m up to 1000 A/m. The transformer
is rated for constant current of 250 A. An internal overtemperature sensor will protect the
transformer. Cause off high primary current a contactor switches on and off the current. This
switch can be operated from the compact NX5/NX7 or NSG 3040A/3060A, while the current
connection is direct from the motor variac (variac NX1-260-16 or VAR 3005A-S16). There
are 2 versions available: MFT 100-120 for 120 V power supply and MFT 100-230 for 230 V
power supply, both devices are optically identical.

check the current with a current probe and adjust the voltage setting.
Using a variac with mains of 100 V or 115 V, the maximum achievable magnetic field is
approx. 750 A/m.
For generate H-fields > 750 A/m it is necessary to connect a booster transformator
