1) Trademark 2) The name and model of the electric energy meter (such as a single -phase fee control intelligent power meter). 3) Measurement License (CMC) Electric energy meters are used for measurement and settlement. It must have a measurement of measurement products issued by the National Technical Supervision Bureau to be legally produced.

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.

Current transformers truly deserve their designation as the "heart" of electricity meters, providing the critical functionality that enables precise energy measurement and fair billing practices. Through advanced engineering, rigorous manufacturing standards, and adaptable designs, these components form the foundation of trustworthy energy management systems. As electrical networks become increasingly complex with the integration of renewable sources and smart technologies, the evolution of current transformer technology will continue to play a vital role in ensuring measurement accuracy, system reliability, and consumer confidence in the evolving energy landscape.

Latching relays have revolutionized energy meter design by combining zero-power holding capability with robust switching performance. Their ability to enhance meter lifespan through reduced power consumption and mechanical durability makes them essential components in modern metering infrastructure. As smart grids evolve toward greater efficiency and functionality, latching relays will continue to play a pivotal role in enabling advanced features while maintaining the reliability expected from critical grid components.
