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

RMU is a ring main unit which is used as a distribution
systems called ring main distributors where the
connectivity of grid is in the form of ring.

Answer / romeo

The use of RMU is to assure the alternative power supply in

We have a 12MW power plant & we inject 5-6MW power to Orissa GRID. For this we have a 33KV/11KV switch yard having 12.5MVA power transformer. Some times we draw power during emergency. It is observed that during Export or Import for load less than 500Kw the power factor is decreasing to 0.3 . This is happening only during export or import. During island condition TG power factor OK.Our capacitor bank is provided with our Power plant auxilliary load. Please suggest how I can we improve our power factor during low load (GRID).
