RMU -- ring main unit
this system is basically for distribution purpose
and in this the feeders are connected in a circuit which is
of ring type.
the main benefit is for future expansion extra feeders can
be added.
and the maintenance can be done easily without any
disturbance

Answer / piyush adroja

ring main unit is a one type of switch and which use in sub
