What is a ring main unit?

A Ring Main Unit (RMU) helps deliver steady electricity by redirecting power during problems, reducing blackouts. RMUs have a looped design, letting electricity take other paths, which keeps the system stable. Important parts of RMUs include circuit breakers, switches, and relays that ensure safety and smooth operation.

What is a ring main unit working principle?

A ring main unit working principle revolves around its ability to distribute power efficiently in an electrical distribution system. It ensures reliability by using a ring configuration that allows electricity to flow through alternative routes. Even if one section fails, power continues uninterrupted.

What is a ring main unit (RMU)?

An RMU, or ring main unit, is a type of medium-voltage switchgear. It consists of one or more circuit-breaker units with associated disconnectors, earthing switches, and instrument transformers. RMUs are commonly used in electrical power distribution systems. A notable application is in wind farms.

How does a ring main unit protect your electrical distribution system?

Overcurrent and short-circuit faults can severely damage your electrical distribution system. To prevent this, the ring main unit incorporates several protection mechanisms. Circuit breakers play a key role by automatically disconnecting the circuit when they detect overload or short-circuit conditions.

Why is a ring main unit important?

Fuses are another critical component in the ring main unit. They protect the distribution network by breaking the circuit when current levels exceed safe limits. Additionally, the RMU is designed to handle ground-fault currents, short-circuit faults, and overloads. These features ensure the safety and reliability of your electrical system.

What is a tower ring main unit?

Our tower ring main unit is a compact, prefabricated MV switchgear unit suitable for installation within wind towers. Some of its key advantages include: At just 500mm wide and 1.6m tall, our 40.5kV tower RMU takes up minimal interior space within wind turbine towers. It is the smallest in the wind power industry.
