Answer / pavan kumar
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.

Answer / vale
The RMU is intended to be used in medium voltage (11KV to
36KV) Ring distribution system in any power
supply/distribution utilities. RMU offers greater
flexibility in supply system in maintaining continuity and
offers practically maintenance free operation. The RMUs are
very compact in size compared to MV switchgear panels.

Answer / subin
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.

Answer / pattabiraman
RMU :-
Normally used by Electricity Boards
Ring Main Unit - Consists of 2 nos Isolators and one No
Circuit breaker. of 200A to 630Amps capacities
2Nos isolators used for Incoming as wells as Out going to
another Ring main unit or vise versa,
The Circuit breaker is common to both Isolators in the RMU
Used as out going to Distribution Transformer

what is a difference b/w earthing & neutral?
why circuit breaker closing time is always higher then tripping / opening time.
How do you protect your appliances from harm in case of neutral failure in a three phase power supply set up.
What is Creepage distance?
what is difference between megger & Contact resistance meter & its Application?
which have higher efficiency transformer or induction moter
what is the basic difference between capacitor and condenser ?
can anyone plz tell me in 3 phase induction motor, whare we use STAR CONNECTED MOTOR and whare we use DELTA CONNECTED MOTOR
Transfer of electric power from primary to secondary in a transformer takes place A electrically B magnetically C electro-magnetically D conductively
Advantages of short circuit and open circuit tests of a transformer?
circuit breaker work alone during fault condition or need any relays ?
why do mostly prefer to generate and distribute electricity in 3 phase..not in 4 phase or 5 phase.??
