A Ring Main Unit (RMU) is a type of switchgear used to control and distribute electricity in a power system. It is also known as a Ring Main Distribution Unit (RMDU). The primary purpose of the RMU is to protect the electrical network from overloading and to isolate faulty sections of the network to ensure an uninterrupted power supply.
Ring Main Unit (RMU) Components Functions Types and Applications - Ring Main Unit (RMU) is a switchgear device used in secondary distribution systems, i.e., between the distribution substation and the end consumer to ensure continuous power supply and isolate the faulty section from the network.
Nowadays Ring Main units are widely used in Metro cities and smart cities for providing reliable supply to the consumers. It is essential for Electrical Engineers to know the working of Ring Main Networks and Ring Main Units. A Ring Main Network is formed by connecting feeders in a fashion to form a loop, and is fed at one or several points.
Ring Main Unit distribution is costly compared to other distribution networks, so this type of distribution can find in urban cities where supply reliability is major issue. Ring main units are available in different voltage ratings ranging from 11KV to 33KV.
Selecting the right Ring Main Unit for your power distribution system is crucial to ensure reliable and efficient operations. Here are some factors to consider when selecting an RMU: Power rating: The power rating of the RMU should match the power requirements of your distribution system.
