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. The main purpose of using a ring main unit is to provide an uninterrupted power supply to consumers even in fault conditions.
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.
When it comes to delivering electricity to people, it's crucial that the process is efficient, dependable, and safe. That's why Ring Main Units (RMUs) have become essential in medium voltage distribution networks. They offer compact and adaptable ways to distribute power.
Ensuring the safety of electrical systems is paramount, particularly when it comes to sophisticated equipment like Ring Main Units (RMUs). The occurrence of an electric arc is a serious concern in electrical switchgear, including RMUs.
Though RMUs are integral to ring network configurations, their utility extends far beyond. Load switch-based high-voltage switchgear has become increasingly prevalent across non-ring distribution systems; hence, the term “Ring Main Unit” has become widely applied to any high-voltage cabinet that predominantly utilizes load switches.
The oil insulated ring main units are commonly seen in mining and oil field applications. Gas insulated ring main units use SF6 S F 6 gas as the insulating medium and are used in low to medium voltage distribution networks to provide uninterrupted power supply and protect the electrical equipment.
When configuring a Ring Main Unit (RMU), some key parameters to consider are: The suitable voltage level to meet the requirements of the specific network. The maximum load that the RMU can handle without compromising performance. The ability of the RMU to withstand and interrupt fault currents.
