In modern power and protection systems, the effectiveness of current transformers depends on two key factors: accurate measurement and stable operation.
HEYI ELECTRIC has been in the industry for decades and has extensive technical and practical experience. Our carefully crafted CP series low-voltage current transformers are specifically designed to provide reliable and accurate current monitoring solutions for various power systems.
1.1 Full range of precision grades, suitable for various uses
Our CP series has prepared different accuracy levels such as 0.2s, 0.5, and 1.0, so no matter where you use them, you can basically choose the appropriate one.
Of particular note is the CP-62/B model, which has a particularly wide current range (5/5A to 150/5A), but can maintain ultra-high precision of 0.2s throughout the entire process. It is particularly suitable for places like electricity trade settlement where there is no room for error.
The CP-80/30 is equally powerful, even with currents ranging from 100/5A to 300/5A, the accuracy remains stable at the 0.2s level. What does this mean? Regardless of the magnitude of the current, our measurements are equally accurate and stable.
1.2 Accurate data measurement is essential for the system to function effectively
Taking the CP-62/20 model as an example, under the commonly used specifications of 100/5A, it not only maintains a high level of precision at 0.2s/0.5s, but also has a particularly low energy consumption (burden) of only 2.5VA.
In this way, when it works in systems such as electricity metering, power monitoring, and protection, the current signals transmitted are particularly accurate and almost error free.
The benefits of accurate data measurement are tangible: on the one hand, in situations like electricity bill settlement that require no difference, it provides technical support, making billing clear and transparent; On the other hand, it is also an important foundation for the efficient operation and refined energy consumption management of the entire power system.
Our CP series has a particularly wide range of current measurement, covering everything from small 5A-100A (such as CP-45/14) to large 400A-3000A (such as CP-100/60).
For example, models like CP-86/60 can not only maintain a high precision of 0.5 level at 600/5A, but also withstand a high load of 7.5VA.
So in places with high requirements such as large industrial equipment, it is particularly suitable and can fully meet the rigorous current monitoring needs.
2.1 Good use of materials is essential for long-term stable performance
For example, our CP-62/30 model uses high-quality silicon steel sheets for the core and PBT flame retardant material for the shell (which has passed the top-level flame retardant standard UL94-V0).
This solid material combination allows it to maintain stable electrical performance even in high current (such as 200/5A to 400/5A) or poor environmental conditions for a long time.
We have practical cases to prove that after five years of continuous use, the accuracy of this model of product is still within the standard range, very durable, and trustworthy.
2.2 Wide temperature adaptability, no matter how complex the environment is
Like the CP-80/40 transformer, it can operate stably with such a large temperature difference from minus 25 degrees to over 75 degrees.
Specifically, at the specification of 200/5A, it can not only maintain high precision of 0.2s/0.5s, but also has particularly low self loss, only 2.5VA; even if the current is increased to 300/5A, the loss is still controlled at 5VA, and the performance is very stable. This also indicates that no matter how the temperature changes, it can maintain stable performance.
2.3 The craftsmanship is solid, making it particularly reassuring to use
The CP-100/60 model is specifically designed for measuring high currents. Even at such a high current of 1000/5A, thanks to our precise manufacturing process, it can maintain stable operation without falling off the chain.
Specifically, at a high precision of 0.2s/0.5s, it can withstand a load of 7.5VA; Even at level 1.0, the load capacity can reach 15VA, indicating that it is fully capable of handling heavy load situations.
It is precisely because of its solid foundation that it has been widely used in industries such as steel and chemical engineering, which require special equipment testing, and has been verified through practice.
3. Multiple application scenarios to assist in the intelligence of the power system
3.1 Establishing a reliable perception foundation for the smart grid
In the distribution system of smart grid, CP-62/B type current transformer is a very reliable choice. It has ultra-high precision of 0.2s, which can provide very accurate current data for intelligent management of the power grid.
Especially in the most commonly used current range of 15/5A to 50/5A, it can not only operate stably all the time, but also has particularly low self loss (only 2.5VA), which ensures that the collected data is accurate and stable from the source.
3.2 Good helpers in the field of industrial automation
In the field of industrial automation, the CP-80/30 product is particularly practical. In the common current range of 150/5A to 300/5A in industry, it exhibits particularly stable performance.
For example, in typical applications such as air compressor monitoring, when the current reaches 250/5A, it can withstand a load of 5VA with an accuracy of 0.2s/0.5s, and can even withstand 7.5VA with an accuracy of 1.0. With such performance as a foundation, it can fully adapt to various requirements for long-term and stable operation in industrial environments.
3.3 Provide accurate data to the energy management system
In the energy management system of large commercial centers, the CP-62/20 transformer plays a crucial role.
It can flexibly match the internal turns (such as 4T, 3T, 2T configurations) within the commonly used current range of 30/5A to 100/5A, ensuring optimal performance and providing highly accurate power consumption data for the entire system.
Especially under the common specification of 60/5A, using a 2T configuration can achieve low loss and stable operation of 2.5VA, ensuring the accuracy and reliability of data collection from the source.
4. Professional service support, working together to create a smart power future
Our CP series current transformers, whether it's the compact CP-45/14 or the powerful CP-100/60, have been carefully designed and rigorously tested. Taking CP-62/30 as an example, under the 400/5A specification, it only bears 5VA at 0.5 level accuracy and only requires 7.5VA at 1.0 level. This solid performance allows it to easily cope with various industrial scenarios.
Our product line is very complete: the exquisite CP-45/14 is designed for precise measurement of small currents ranging from 5A-100A; The CP-62/B with wider coverage can achieve high-precision measurement of 0.2s throughout the 5A-150A range; CP-62/20 covers the range of 30A-200A and provides multi turn configuration, with high flexibility; For commonly used industrial current ranges, CP-80/30 has a wide range of 100A-300A, with stable and reliable performance; There is also the CP-100/60 specially designed for high current scenarios, which can provide reliable monitoring for 400A-3000A high currents.
No matter what your needs are, we can provide suitable products and comprehensive technical support.
