A Smart Ring Main Unit (RMU) is an advanced electrical distribution device that integrates switching and protection functions in a compact, modular design. Equipped with intelligent sensors and communication capabilities, Smart RMUs enable real-time monitoring, remote control, and automation of electrical networks.

 They enhance grid reliability, efficiency, and safety by providing detailed insights into network performance, facilitating predictive maintenance, and allowing for swift fault detection and isolation. Ideal for urban and industrial applications, Smart RMUs are a key component of modern smart grid initiatives.
