A 10A miniature current transformer (CT) is a compact, precision instrument designed to measure alternating current (AC) in low-voltage electrical systems. Unlike traditional CTs, which are often bulky, this miniaturized version is engineered for applications where space constraints and portability are critical, such as in industrial control panels, renewable energy systems, and consumer electronics.

The accuracy is unchanged for a long time, and there is no need to run the school, no installation and transportation, etc.

As an intelligent product developed by new technology, smart electricity meter can complete the contact function between users and smart grid. It not only has the function of human-computer interaction, but also has the basic function of electricity energy measurement, information transmission and remote status monitoring.

This exhibition will focus on:Power plant products and equipment systems: power devices, high voltage switches, transmission, distribution network, transformers, current transformers, voltage transformers, power capacitors, high voltage cabinets, monitors, electrical engineering, power supply and accessories, wires and cables, insulation materials, measurement and electronic equipment systems, etc

​Smart meter is a metering device that can measure electricity remotely through RS485 data transmission and terminal computer software management. Free automatic power off, timed power off, student apartment malignant load identification and other functions.

In conclusion, the Liquid Crystal Display in a smart meter is a highly engineered subsystem that balances stringent technical demands with user-centric functionality. It must deliver clear, always-available information with negligible power draw, while surviving decades of environmental stress. Evolving from a simple numeric readout to a versatile information hub, it is key to user engagement, utility operations, and value-added services. The adoption of robust technologies like COB and deep customization ensures that the display is not a commodity component, but a reliable, integral, and future-ready interface that defines the user's experience and trust in the metering device throughout its exceptionally long service life.

Oswell’s evolution from a smart meter component specialist to a key player in the EV charging ecosystem is a masterclass in strategic technological leveraging. It is not a story of abandoning a core competency but of recognizing and activating deep technological synergies. The company’s DNA in precision measurement, robust power management, and reliable communication​ provided the perfect gene pool for innovating in the adjacent field of smart energy transfer. This unique position allows Oswell to deliver charging solutions that are not just powerful, but are inherently smarter, more reliable, and more seamlessly integrated into the broader energy infrastructure—from the meter on the wall to the charging pile in the lot. In an industry racing towards an electrified future, Oswell demonstrates that sometimes, the most powerful forward leap comes from a deep understanding of the fundamental currents that have always powered progress.

Oswell's split-core current transformers represent more than just a convenient tool; they are an enabler of the modern, data-driven approach to energy management. By solving the critical problem of installation downtime, they transform energy monitoring from a disruptive, high-cost project into a seamless, value-adding service. This technology empowers organizations to gain immediate visibility into their energy consumption, make informed decisions that reduce costs and carbon footprint, and build more resilient and efficient operations—all without flipping a single switch to "off."

Latching relays are not merely components but enablers of efficiency, accuracy, and reliability in energy metering. Their bistable operation ensures minimal power consumption, their inherent memory function guarantees accurate tariff application, and their robust design delivers long-term safety and cost savings. The integration of high-performance latching relays from specialized manufacturers like Oswell​ is, therefore, a critical design choice for developing next-generation metering devices that meet the evolving demands of modern energy management systems.

The convergence of IoT technology with traditional meters and transformers represents a paradigm shift in energy management, enabling unprecedented levels of visibility, control, and efficiency. These intelligent devices form the foundation of smart grid infrastructure, supporting more resilient, sustainable, and cost-effective energy systems. As technology continues to evolve, IoT-enabled energy equipment will play an increasingly vital role in managing the complex energy challenges of the future.
