ring main unit in electrical power distribution
A standard piece of switchgear in distribution systems comprising of switches for switching power cable rings and of switches in series with fuses for the protection of distrbution transformers. RMU: Ring Main Unit. RMU used for H.T.side. RMU is having 3no.s of switches(Circuit Breakers or Isolators or LBS), it is used for two inputs with mechanical or electrical interlock and one outgoing to the load. Either one input with two outgoings. RMU used for redundancy feeder's purpose.
Ring main unit is used in a secondary distribution system. It is basically used for an uninterrupted power supply. Alongside, it also protects your secondary side transformer from the occasional transient currents. Depending on your applications and loading conditons you can use a swicth fuse combination or a circuit breaker to protect the transformer. This transformer connected to the switch fuse/ circuit breaker is called your T off. In a common arrangement you have Load break swicthes on both the sides of your T off. Ring main Units come in standard ratings of 11/22/33 kV, 630/1250 A, 21 KA/3 secs.

-Safety enclosed boards are used for most new installations. Common terms used to designate equipment of this type are metal-enclosed switchgear and metal-clad switchgear.
Most safety enclosed boards are of the unit or sectional type. They consist of a combination of the desired number and type of standardized unit sections.
Each section is a standard factory-assembled combination of a formed steel panel and apparatus mounted on a steel framework.
Safety enclosed switchgear may be classified with respect to purpose of application as follows:
1. General medium- or high- voltage switchgear
2. Primary unit substations
3. Rectifier unit substations
4. Secondary unit substations or power centers
5. General low-voltage switchgear
6. Low-voltage distribution switchboards
7. Motor-control-center switchboards
[American electricians’ handbook]
Medium-voltage switchgear (Fig. 4.115) provides for the required control and metering equipment for generators, transformer supply circuits, feeders, large motors, etc., for systems with voltage up to 15,000 V. A large variety of standardized units is available
