High-precision transformers optimized for the Nordic power grid and Swedish industrial standards.
Sweden stands at the forefront of the global energy revolution, driven by its ambitious goal to achieve a 100% renewable energy system by 2040. In this context, the demand for High Accuracy Zero Phase Current Transformers (ZPCT) has surged. These components are critical for monitoring leakage currents and ensuring the safety of advanced electrical grids, particularly in Sweden’s expansive wind farms and hydropower stations.
As a leading manufacturer and exporter, we recognize that the Swedish industrial landscape—led by giants like ABB, Ericsson, and Northvolt—demands unprecedented precision. Our ZPCTs are designed to meet the rigorous SS-EN standards, providing reliable residual current detection that is essential for both residential RCDs and large-scale industrial protection systems. From the urban smart grid initiatives in Stockholm Royal Seaport to the heavy industrial mining operations in Kiruna, our transformers provide the accuracy needed to prevent electrical faults and optimize power quality.
The trend in Sweden is moving rapidly toward Industry 4.0 and IoT integration. Modern power systems require "Smart" sensors. Our latest Zero Phase Current Transformers are not just passive components; they are engineered to work seamlessly with digital transducers and wireless energy monitors, enabling real-time data analytics for Swedish utility providers and facility managers.
Fujian Smrtr Technology Co., Ltd. (Zentar®) has been a cornerstone of the magnetic component industry since 1993. As a premier exporter to the Swedish market, we bring decades of specialized expertise in designing high-accuracy current transformers that withstand the harsh Nordic climates and meet strict European safety certifications.
We specialize in magnetic ring cores and current transformers for electrical safety and power metering. Our split-core current transformers and Rogowski coils are widely used for energy efficiency monitoring in Stockholm’s commercial buildings and peak load analysis in Sweden’s manufacturing sectors.

In the Swedish market, the integration of EV charging infrastructure is a massive driver for high-accuracy zero-phase current transformers. As Sweden transitions to electric mobility, every charging station requires precise residual current monitoring to protect users and the grid from DC leakage. Our ZPCTs are optimized to detect even the smallest imbalances, ensuring compliance with international safety standards.
Furthermore, the HVDC (High Voltage Direct Current) projects connecting Sweden to neighboring countries require specialized instrument transformers. Our 12kv to 75kv insulation series are specifically designed to handle these high-demand environments. By using ferrite cores and advanced silicon steel, we minimize phase shift and maximize linear response, which is crucial for the high-frequency harmonics often found in modern Swedish power electronics.
In the Swedish context, "High Accuracy" translates to "High Reliability." A difference of 0.1% in accuracy can mean the difference between a safe shutdown and a catastrophic system failure in a sensitive data center or a large-scale manufacturing plant in Uppsala or Västerås.
Diverse configurations for metering, protection, and monitoring.
As Sweden expands its wind power capacity in the Norrland region, our Zero Phase Current Transformers provide critical earth leakage protection in turbines, ensuring that ground faults are detected before they cause equipment damage or downtime.
In dense urban environments, sub-metering and energy efficiency are paramount. Our split-core designs allow for easy retrofitting into existing electrical cabinets without power interruption, making them ideal for Stockholm’s green building initiatives.
Swedish industry relies on heavy machinery where electrical faults can be life-threatening. Our high-insulation transformers (up to 75kv) ensure that safety systems remain operational even in high-EMI environments common in Swedish manufacturing.
