Current transformer is an important type of measuring transformer, mainly used to convert large current into small current in proportion for measurement, protection and control. Our current transformers adopt advanced electromagnetic induction technology, using high-quality iron cores with high magnetic permeability and high-performance winding materials. They have high conversion accuracy and good linearity, and can provide accurate current signals for the power system. They are essential key equipment for power measurement and monitoring.
Product Advantages and Features
1. High precision measurement: using advanced winding technology and high-quality magnetic materials, the accuracy level can reach 0.2S, and the current can be accurately measured. Within the rated current range, the measurement error is controlled within ± 0.2%, providing reliable data for power measurement.
2. Wide range: The range covers from 5A to 5000A, meeting the measurement needs of different power systems and equipment. Whether it is small civilian equipment or large industrial facilities, they can find suitable ranges and have a wide range of applications.
3. Good anti-interference ability: adopting special shielding technology to effectively resist external electromagnetic interference, ensuring stable and accurate current signal output in complex electromagnetic environments, and ensuring stable operation of the power system.
4. High insulation performance: The insulation material is made of high-quality epoxy resin, with an insulation level of 35kV, which can effectively prevent leakage and breakdown phenomena, ensure equipment and personnel safety, and adapt to power systems of different voltage levels. (Keywords: high insulation current transformer, safe and reliable)
5. Long life and stable operation: After rigorous aging and durability testing, the average time between failures exceeds 100000 hours. Key components are made of wear-resistant and corrosion-resistant materials, reducing maintenance frequency and lowering usage costs.
