Founded in 1998, Hubei Tianrui Electronic operates under the brand PowSen, a national high-tech enterprise and national specialized, refined, distinctive “little giant” manufacturer fully focused on R&D, mass production and global sales of current transformers, current transducers and supporting electrical sensing components. For 28 years, we have delivered reliable current measurement solutions for power grids, industrial automation, rail transit, new energy and smart building sectors worldwide, building long-term cooperation with top brands including ABB, Siemens, 3M and ChintHubei Tian....
Our manufacturing strength stands out in scale and automation. We own three subsidiaries and self-built factory spaces covering over 37,000 square meters, employing more than 300 staff members, among whom a dedicated 50+ R&D team leads technical innovation. Equipped with over 1,000 sets of automated production lines and precision testing instruments, our annual output hits 15 million units of transformers and sensors, supporting stable bulk orders and customized small-batch demands. We hold more than 60 authorized patents covering invention, utility model and appearance designs, including core technologies of split-core installation, closed-loop Hall compensation and anti-saturation Rogowski coils, forming independent intellectual property barriers in current sensing field.
Our two flagship product lines are current transformers and current transducers, covering full measurement scenarios for AC and DC signals.
Current Transformer Series
Based on electromagnetic induction principle, our CT portfolio includes solid-core miniature CT, split-core openable CT and Rogowski coils. Split-core transformers enable cable installation without power cut, greatly lowering renovation costs for energy monitoring projects. Rogowski coils eliminate magnetic saturation and deliver ultra-wide frequency response, ideal for high transient current testing in wind and solar power stations. All CTs offer multiple core sizes and transformation ratios to match smart metering, relay protection and power distribution cabinet systems.
Current Transducer Series
Our high-precision current transducers adopt Hall effect and magnetic compensation technology to convert raw AC/DC current into standard 4–20mA, 0–10V or RS485 digital output signals. The lineup also integrates voltage transducers and all-in-one power transducers that calculate active/reactive power simultaneously. Featuring high isolation, low temperature drift and DIN rail quick mounting, these transducers serve real-time monitoring for EV charging piles, factory robotic lines and communication data centers. We support personalized parameter adjustment, housing size and signal output customization to satisfy unique industrial project requirementsHubei Tian....
Our products feature three core competitive edges: ultra-high measurement accuracy, flexible multi-specification selection and convenient maintenance-free installation. They have been widely deployed across global industries: smart grid energy metering, railway traction monitoring, wind & solar new energy, industrial automated production, new energy vehicles, communication base stations and intelligent building power management. Every product undergoes strict aging, insulation and electromagnetic interference testing before delivery to guarantee long-term stable operation in harsh working environments.
Adhering to the vision of building a green smart sensing ecosystem, PowSen integrates R&D, intelligent manufacturing and full-cycle after-sales service. As a one-stop manufacturer of current transformers and current transducers, we keep optimizing production efficiency and technical performance to provide cost-effective, reliable current measurement solutions for global industrial and energy customers.
