Why do we need ring main unit (RMU). what is its purpose and its advantages . what is the operating function of rmu
Answer Posted / kj
Usually a RMU is used to allow a feed of supply from 2
directions and tapping of to a transformer, etc.
Each of these supplies may have a number of RMU's in series
forming a ring. If a section of the feeder needs to be
isolated due to work or failure an RMU on each end of this
section can be opened without stopping any supply.

a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
