Metered Ring Main Unit (MRMU) T&C Method Statement

In an electrical power distribution system, a Ring Main Unit (RMU) is a factory assembled, metal enclosed set of switchgear used at the load connection points of a ring-type distribution network.

In this article, we will see together the method statement step by step for T&C MRMU.

Smart Ring Main Unit in Projects

Ring main units are used in the ring main network.

They connect feeders to form a loop and monitor faults or any malfunctions at the feeders and distribution transformer end.

Plus, we use them to ensure power is provided to the utility without disturbance.

GIS RMU Components

* GIS = Gas Insulated Switchgear
* RMU = Ring Main Unit
* The gas type used in GIS is SF6

* The gas is secured in a stainless steel tank and contains the following:
- The busbar of the panel.
- All live switching components


* The number of compartments in RMU depends on no. of In/Out Cells
