III. Permeability range of Low permeability nanocrystalline cores
1. Ultra-low core loss
100 KHz, 200 mT. Pcv≤200 mW/cm3.
It is better than the power ferrite PC48 material, less than 300 kHz, and has the lowest
loss among all current soft magnetic materials. Its loss is about 1/10~1/20 of MPP
materials.
2. High Bs
Bs is about 1.25 T, and is about 3 times of the power ferrite, which is also higher than
MPP materials. Its anti-saturation ability is significantly higher than that of ferrite material
and MPP materials with the same permeability and power.
3. Constant magnetic permeability
Compared with nanocrystalline materials with high permeability, its variation of
permeability with frequency is small.
4. Excellent temperature stability
At -40 ℃~150 ℃, the permeability changes in about 30%, which is significantly better
than the power ferrite high permeability material.

Typical application
V. Application areas
Brief introduction: The current and voltage in
the power supply line are quite different, which
needs to be converted into a relatively uniform
current for the convenience of secondary
instrument measurement.In addition, the voltage
on the line is relatively high, so the direct
measurement is very dangerous. it requires an
electrical device which converts large current into
small current signal and acts as electrical isolation,
namely current reverser.
The national standard standardization
organization defines it as: A specia l
transformer that supplys power for measuring
instruments, instruments, relays, and other similar
appliances.

V. Application areas
Applications:
Electronic energy meter, precision
power meter, power transmitter,
current and voltage data acquisition,
relay protection, power transmitter,
ser vo motor, power monitoring
equipment, power system and other
d i g i t a l e l e c t r i c a l m e a s u r i n g
instruments, meters, intel l igent
electric control cabinet.
(1) Current reverser
V. Application areas
Constitution: It consists of two parts: the core and windings. Windings are
divided into primary and secondary windings. Primary winding is usually single turn or
several turns, and the turns of secondary windings is often more. The specific number
of turns is determined by the designed ratio of turns. It can be wound after setting the
precise number of turns by the automatic winding machine, and tested by the mutual
inductor coil number tester after winding to ensure the correctness of the coil turns.

V. Application areas
Advantages:
1. High Bs. Strong resistance to current saturation, suitable for measuring strong
DC component current, especially more than DC 50 A.

V. Application areas
Advantages:
2. Compared with Mn-Zn ferrite and high permeability nanocrystalline soft magnetic
cores, low permeability nanocrystalline cores don't need open a local air gap to
improve the anti-saturation capability, so that don't need expensive magnetic
shielding.
3. Low remanence, low loss, Br<20 mT, the remanence of nanocrystalline with
magnetic permeability of 200 is even lower than 3mT, and the effective local
permeability is very close to its linear permeability, and low magnetic loss, 100 kHz,
200 mT, the loss≤200 mW/cm3, which are beneficial to limit the phase deviation
between current and voltage of sensors, and reduce temperature rise to increase
accuracy.

V. Application areas
Advantages:
4. Excellent temperature stability. The variation of µ between -40 ℃ and 120 ℃ is less
than 25%, and the change of µ with temperature is regular and almost linear, which is
beneficial to improve the limited working temperature and measurement accuracy of
measuring equipments.

V. Application areas
Advantages:
5. Not easy to age above 100 ℃.
The low permeability nanocrystalline can be in the temperature environment above
100 ℃ for a long time, and the permeability variation is less than 1%, which is
conducive to improving the measurement accuracy in the high temperature
environment. Low permeability Co-based nanocrystalline cores' Bs is around 0.8 T,
which is not only lower than 1.25 T of low permeability nanocrystalline cores, and
more likely to be saturated, but also more likely to age above 100℃. Therefore, low
permeability nanocrystalline is an ideal alternative material for low permeability Co-
based nanocrystalline.
