Digital Multifunction Measurement and Control Meter, GW-LM72/LM92 Series

The GW-LM72/LM96 series of digital multifunctional measurement and control meters are built around an industrial‑grade microprocessor, delivering high processing speeds and exceptional cost‑effectiveness. These meters provide highly accurate measurements of three‑phase and single‑phase voltage, current, power, and other fundamental parameters, along with features such as set‑point over‑limit alarms. Data exchange with a host computer is enabled via RS‑485 communication, supporting intelligent energy management.

Protection, Measurement, Control, and Automation Device GW-LR60/LR51 Series

The GW-LR60/LR51 series of protection, measurement, and automation devices is a new-generation microprocessor-based relay protection system specially developed by the company to meet the requirements of power systems for relay protection. This series includes the GW-LR60, GW-LR60-L, GW-LR51-A, and GW-LR51-G models, providing comprehensive protection functions for primary equipment such as 35 kV and lower‑voltage lines, transformers, motors, capacitors, and feeders.

GW-SC Series Intelligent Operation and Display Device for Switchgear

The GW‑SC series products provide centralized indication of the primary circuit's simulated status, the position of the handcart, the positions of the isolating switch and earthing switch, the switch status, and the energy‑storage status of the operating mechanism. They also feature high‑voltage live‑indication, live‑lockout output, automatic heating and dehumidification, real‑time digital display of temperature and humidity, heater‑fault monitoring, over‑temperature alarm with forced shutdown of the heater, intelligent voice‑based error‑prevention prompts, on‑line temperature measurement of in‑cabinet electrical contacts, and an RS‑485 communication interface, among other functions. These features simplify the design of switchgear panels, enhance the overall appearance, and improve both switch‑status indication and safety performance.
