AI Overview
This video shows how to build a current sensor with a similar core:
Key Advantages for Current Sensors:
- High Permeability/Low Loss: Ideal for high-accuracy power metering.
- High Sensitivity: Ideal for detecting small current fluctuations.
- Low Core Loss: Excellent temperature stability and reduced eddy current losses.
- Frequency Range: Suitable for 50/60 Hz and higher frequencies (e.g., in GFCI coils).
- Application Areas: Common in precision current transformers, clamp meters, and Hall effect sensors.
Key Manufacturers/Providers:
- Jiangsu Hongyun Precision Industry Co., Ltd. (Hongertech): Specializes in NiFe-based Permalloy Cut Cores and Mu Metal cores for high-accuracy current transformers.
- Ironcore Technology Co., Ltd.: Offers various permalloy cores for current sensors.
- Xiamen ZTC Technology Co.,Ltd.: Produces permalloy cores, including those for zero-phase current transformers.
- HemeIct: Produces CE-certified Permalloy Cut Cores for audio and general current transformers.
Common Specifications:
- Material: 1J85/1J79 (NiFe) or 80% Nickel Permalloy (Mu metal).
- Shape: Cut core allows for easier assembly around conductors.
- Operating Temperature: Generally suitable for -35°C to 70°C, suitable for outdoor/industrial environments.
These cores are particularly useful when a sensor requires a very low magnetic loss to ensure precision in current, power, or energy monitoring.
