Nanocrystalline Split Core For Current Sensor

Nanocrystalline Split Core For Current Sensor


Power inductors, current sensors, and split core magnetic cores are just few of the many applications for Nanocrystalline split core. A superior alternative to both split silicon steel core and permalloy core, this material offers several advantages. Standard CTs with a nanocrystalline split core provide a linear voltage output that is precisely proportionate to the input current.

· It has ten times the permeability of a divided silicon steel core.

· In comparison to a split silicon steel core, the core loss is reduced by a factor of 0.3.

· Compared to a split permalloy core, the cost is cut in half.

Split-Core Current Sensors are useful when rethinking preexisting systems where the status quo must be preserved. They provide the option of opening on one or both sides, making them suitable for use even in confined quarters. Current sensors with a nanocrystalline split core are designed for retrofitting into existing facilities, where their installation would be impeded by the removal of transport bar/link carriers.

High Accuracy Factory Split Core Current Transformer


The ever-increasing need for installation into preexisting networks inspired the development of the Split core current transformers by Coilcore. The labor costs associated with our Split Core (open-able) CTs have the potential to be reduced overall. It is enough to only clip them around the wires being read.


 Zip ties may hold things in place, so cables and busbar circuits can be connected. The Split Core Current Transformer is appropriate for indoor units with a rated voltage of 10KV or below. Its functions include controlling and measuring circuits, measuring line transformations, and providing protection.



You may order them in whatever form you choose, such a Toroidal, shape, clamp-on shape, or another.

· Inductors or Current Sensors to Measure Power Flow


· Nanocrystalline cores, when split, have a permeability that is 10 times that of silicon steel cores.

· When compared to silicon steel, the core loss of a nanocrystalline core that has been split is reduced by a factor of 0.33.

· The split nanocrystalline core is 50% less expensive than the permalloy core.


After nanocuttering, the permeability may reach values as high as 6,000. Accuracy may be raised by a whole tier. The core loss at 16kHz/37mT is one-sixth that of silicon steel and one-half that of an amorphous core. Reduce the efficiency with which heat is released from the final product. Extend its usefulness. Linearity is 20% better than that of a split silicon steel core. 


It is common knowledge that the CT core permeability should be as high as possible to get the lowest possible measurement error and the highest possible measurement accuracy. Under low Ampere-tums or small turn ratios, the silicon steel CT core cannot provide the required level of measurement precision. In addition, the Fe-Ni Permalloy core has a restricted applicability because it has a low saturate induction and a high price. 


Because of their high permeability, high magnetization, and lower cost in the field of power supply systems, power energy measurement and control systems, dynamical systems, relay protection, and other areas, nano-crystalline cores are gaining wider usage for the 0.2,0.2s, and 0.1 accuracy grade special current transformers. This is due to their high permeability and high magnetization



1. Keep the straightforward design of older C kernels.

2. The clamp-on core design is more secure, less time-consuming to install, more transportable, and more convenient for adjusting the inductance without turning off the mains power.

3. Nanocrystalline materials have a high permeability and may be used to make precise comparisons to other materials.

4. Huge market opportunity for energy efficiency and environmental protection



Split-core current sensors can be mounted to existing panels, such as control centers or load centers, to measure or monitor wattage. Which is widely used for:

· Current Measurement

· Electrical loading monitoring

· Energy and sub-metering products

· Network equipment

· Instruments and sensors

· Control System


Nanocrystalline Split Cores for Current Sensors and Common Mode Filters

Due to their high permeability, low power loss, and high saturation, nanocrystalline cores are a popular option for common mode choke (CMC) applications. Nanocrystalline common mode chokes have many uses beyond only electronics, including automotive and welding equipment, solar inverters, frequency converters, EMC filters, and switched-mode power supplies (SMPS). Nanocrystalline cores provide a greater impedance at high frequencies and a broader operating temperature range than ferrite cores.

· Key Characteristics

CMCs can reduce their footprint while still handling larger currents because of the excellent permeability of their nanocrystalline cores. CMCs with nanocrystalline cores are more resistant to current imbalance and performance degradation at high temperatures due to their 1.25T saturation induction and broad temperature range. Cores may be wound with thick wire thanks to the material's low AC losses, and long-lasting polyester (130°C) and rynite polyester (155°C) casings further improve efficiency.

To further serve our customers' needs, Transmart is developing new nanocrystalline products for use in the following fields:

· Current AC Detectors

· Sensors that Detect a Current in Which None Is Flowing

· Sensitive DC Current Detectors

· Cores of cut current sensors in Hall Effect Sensors
