Current and Voltage sensor (CVs) for Distribution Transformers in Thailand

Wenzhou Heyi Electrical Co., Ltd., relying on its excellent R&D strength and industry experience, has reached a cooperation with Thailand PEA/MEA Power Bureau to provide innovative cast transformer solutions for its new power monitoring project.

This series of products has dual signal output, high reliability, and long-term stable outdoor operation as its core advantages, injecting strong power into the construction of smart grids.

Cast outdoor ring current transformer secondary bushing phase A B C helps Thailand power intelligent upgrad.



1. One machine with two uses, efficient integration

The transformer developed this time breaks through the traditional single signal acquisition mode, and innovatively realizes the output of current signal while the other terminal can take the voltage signal.

The same device can complete the accurate acquisition of dual parameters, greatly simplifying the installation process and reducing the
redundancy cost of equipment.

A transformer only needs to be equipped with 4 transformers to meet the full range of data acquisition needs, helping to improve the monitoring efficiency of the power system.

2. Casting process, no fear of harsh environment

For the hot and humid outdoor environment with a lot of salt fog in Southeast Asia, the product adopts integrated epoxy resin vacuum casting technology to form a fully enclosed protective structure, which completely eliminates moisture penetration, ultraviolet erosion and chemical corrosion.

The internal precision components are completely isolated from the outside world, and the weathering resistance is enhanced, which can ensure longer stable operation time in extreme environments and significantly reduce the frequency of equipment maintenance and the cost of the entire life cycle.

3. Multi-specification adaptation, flexible empowerment of the power grid

To meet the needs of different scenarios, the product provides multiple ratio models of 100/5A, 150/5A, 250/5A, 400/5A, and 600/5A, covering the entire scene from low-voltage power distribution to medium and high-voltage power transmission and transformation.

The precise measurement accuracy and wide dynamic range characteristics ensure the data reliability from light load to overload conditions, and provide solid data support for the remote monitoring system.

4. "Nerve endings" of smart grids

As a key component of the intelligent transformation project of the PEA/MEA Power Bureau of Thailand, this series of transformers collects current and voltage data in real time and transmits it to the central monitoring platform to realize dynamic analysis of power loads, fault warnings and remote control.

Its anti-interference design can effectively resist electromagnetic noise, ensure zero distortion in signal transmission, and help build an efficient and safe power Internet of Things network.

Heyi Electric has always taken technological innovation as its engine and customer demand as its orientation.

This cooperation not only demonstrates the competitiveness of China's smart manufacturing in the international power market, but also marks another breakthrough of the company in the field of intelligent sensing.

In the future, we will continue to deepen our global layout and provide more customers with cost-effective power monitoring solutions.
