Flexible Rogowski Coil Current Transformer Vietnam

Leading Supplier of High-Precision Energy Monitoring Solutions for Vietnam's Industrial Smart Grids & Automation.

🚀 The Evolution of Current Sensing in Vietnam

Vietnam is currently undergoing a massive industrial transformation. With the implementation of Power Development Plan VIII (PDP8), the country is shifting rapidly toward renewable energy and smart grid infrastructure. Traditional solid-core current transformers (CTs) often struggle with the spatial constraints of Vietnam's existing urban substations and the high-frequency harmonics of modern solar farms in provinces like Ninh Thuan and Binh Thuan.

Our Flexible Rogowski Coil Current Transformers provide the perfect solution for the Vietnamese market. Unlike traditional CTs, our coils are lightweight, flexible, and can be installed without disconnecting the primary conductor. This is critical for Vietnam's "always-on" manufacturing sectors, such as electronics assembly in Bac Ninh and textile production in Binh Duong.

  • 🔹 No Magnetic Saturation: Ideal for measuring high currents in Vietnam's heavy industries.
  • 🔹 Easy Retrofitting: Perfect for upgrading older Vietnamese power distribution boards.
  • 🔹 High Accuracy: 0.5% precision for billing and energy auditing.

📈 Industrial Trends & Applications in Vietnam

How our Rogowski technology is powering the "Made in Vietnam" revolution.

⚡ Smart Factory Retrofitting

In industrial zones like VSIP (Vietnam Singapore Industrial Park), factories are adopting IoT-based energy management. Our flexible coils allow for non-intrusive installation on existing busbars, enabling real-time monitoring of energy consumption without downtime.

☀️ Renewable Energy Integration

Vietnam leads Southeast Asia in solar and wind capacity. Our Rogowski coils are essential for measuring the complex AC waveforms and high-frequency harmonics generated by large-scale inverters in solar farms across Central Vietnam.

🚗 EV Charging Infrastructure

With the rise of VinFast and the expansion of EV charging networks in Hanoi and Ho Chi Minh City, our leakage current detection sensors ensure the safety and efficiency of high-speed charging stations.

🏢 Commercial Building Efficiency

Modern skyscrapers in Da Nang and HCMC use our 3-in-1 three-phase flexible CTs for sub-metering, helping property managers achieve LEED certification and reduce operational costs.

🛠️ Precision Manufacturing & Quality Control

Our state-of-the-art facility ensures every Rogowski coil meets international standards for the Vietnam market.

💡 Why Rogowski Coils are the Future of Vietnam's Energy Management

As Vietnam continues to integrate more renewable energy sources into its national grid, the need for accurate, flexible, and reliable current measurement has never been higher. Traditional iron-core transformers are often too bulky and prone to saturation when dealing with the non-linear loads typical of modern Vietnamese industrial parks.

Our Flexible Rogowski Coil Current Transformers offer a linear response across a wide range of currents, making them ideal for harmonic measurement and power quality analysis. Whether you are a utility provider in Hanoi looking to monitor substation health or a factory manager in Binh Duong seeking to optimize energy costs, our technology provides the data you need to make informed decisions.

Key Benefits for Vietnam Suppliers & Factories:

  • Space-Saving Design: Fits into tight electrical cabinets common in Vietnam's urban infrastructure.
  • Safety First: No danger of open-circuited secondaries, ensuring the safety of Vietnamese electrical technicians.
  • Wide Dynamic Range: Measure from a few amps to hundreds of kiloamps with the same sensor.
