As global power grids transition toward decentralized "Smart Grids," the demand for non-intrusive, flexible current sensing has skyrocketed. Rogowski coils offer the perfect balance of accuracy and ease of installation for retrofitting existing infrastructure.
With the rise of Solar PV systems and Wind energy, measuring high-frequency harmonics and transient currents is critical. Flexible Rogowski coils are preferred for their lack of magnetic saturation, allowing for precise measurement of massive current surges in renewable sites.
Modern factories integrate sensors into their ERP and energy management systems. Our Rogowski coils provide the "data pulse," enabling real-time monitoring of machine health and predictive maintenance through precise current profile analysis.
Fujian Smrtr Technology Co., Ltd. (Zentar®) is a leading manufacturer of magnetic components for electrical safety and power measurement, established in 1993. With over three decades of experience, we have grown into a powerhouse with operating facilities in Xiamen, employing approximately 410 dedicated professionals.
Our commitment to excellence is reflected in our robust infrastructure, covering 40,000 square meters of workshop space. We specialize in the consulting, design, and manufacturing of current transformers, RCD fused connection units, and wireless energy monitors. We are one of the leading suppliers of protection against electric shock and electrical faults.
Global real estate developers and facility managers require Custom OEM Rogowski Coils for cost allocation in shopping malls and office towers. Our coils wrap easily around large busbars without disconnecting power, saving thousands in labor costs.
In regions like Europe and North America, heavy industries (Steel, Automotive) use our High-Frequency Rogowski Sensors to monitor harmonics and transients that could damage sensitive machinery.
The global shift to Electric Vehicles has created a surge in demand for compact, highly accurate current transformers for Level 3 DC fast chargers and residential charging stations.
With our D-Src 36kv High Voltage series, utility companies in Southeast Asia and Latin America are upgrading their substation monitoring to prevent catastrophic failures during lightning strikes or surge events.
Under the IATF 16949 and ISO9001 quality management systems, Smrtr Technology ensures every coil meets stringent international standards. Our ERP-managed production minimizes lead times and maximizes reliability.
Our team is led by professors and 20 senior engineers who provide workable solutions and technical support. We don't just sell products; we solve complex engineering challenges.
Located in Xiamen, we have access to the world's most efficient logistics networks, ensuring short lead times and competitive shipping costs for our global exporters.
By utilizing Eight Axis Winding Machines and automatic testing equipment, we eliminate human error and ensure that every unit of our 50 million annual capacity is flawless.
