6 FAQs about [Project Introduction of Solar High Current Ring Main Unit]

What is a ring main unit?

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.

What is ring main unit (RMU)?

Ring Main Unit,RMU is a compact, enclosed and sealed type of Switchgear used for medium voltage power distribution. It is a complete Switchgear in itself. A complete Switchgear means, assembly of required switching devices, protection device as well as metering device.

How do I choose the right ring main unit?

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.

What is SF6 ring main unit (RMU)?

A simplified schematic diagram of RMU is shown in figure below. The incomer as well as outgoing feeders are enclosed in an SF6 environment as to make the design compact. Compatible instrument for monitoring of SF6 gas pressure is mounted on the Ring Main Unit, RMU to monitor the gas pressure.
