Multifunction Network Power Meter

The power meter is specifically designed for power monitoring applications in power systems, industrial and mining enterprises, public facilities, and smart buildings. It can measure a wide range of standard electrical parameters, including current, voltage, frequency, power factor, active and reactive power, active energy, and reactive energy. Equipped with digital input/output, energy pulse output, and an RS‑485 communication interface, it supports remote data transmission. Optional features include analog output, harmonic analysis, multi‑tariff energy accounting, and event logging. The product is widely used in energy management, substation and distribution network automation, residential community power monitoring, industrial automation, smart buildings, and intelligent switchboards and switchgear.

Microcomputer-based Integrated Protection and Control Device

The 6600 microcomputer-based integrated protection and control device is a next-generation microprocessor‑based relay protection system specially developed by our company to meet the relay protection requirements of power plants, substations, distribution stations, and other facilities within the power system. It provides comprehensive protection functions for primary equipment such as overhead lines, cable lines, transformers, and capacitors at voltage levels of 35 kV and below, and can be installed either locally in switchgear cabinets or centrally on protection panels. Its robust design ensures long‑term, reliable operation even under harsh environmental conditions.

Intelligent Control of Switchgear

The intelligent control device for switchgear is an innovative product developed by our company to provide convenient operation and dynamic simulation indicators for various switchgear in power systems. It is primarily designed for indoor switchgear with voltage ratings ranging from 0.1 kV to 40.5 kV. This device integrates multiple functions, including primary circuit status simulation, handcart position monitoring, circuit breaker position indication, isolator position detection, earthing switch position verification, spring‑energy storage status monitoring, high‑voltage live‑indication, electromagnetic interlocking for high‑voltage energization, temperature and humidity control, heater fault monitoring, as well as over‑temperature alarm and automatic shutdown of the heater. When selecting this product, users need only provide a single‑line diagram.
