A fault-tolerant system is achieved through the redundancy of uninterruptible power supplies (UPS), which maintain power continuity in the event of a failure.
[DELTA ELECTRONICS, INC.]Отказоустойчивость системы достигается за счет резервирования источников бесперебойного питания (ИБП), обеспечивающих непрерывность электропитания при нарушении в сети электропитания.

True redundancy using a CP-A RUFor true redundancy it is necessary to provide decoupling of the individual power supplies.
Otherwise, the failed power supply could possibly act as a load for the other power supply or, in the worst case, cause a short circuit on the secondary side resulting in a failure of the second power supply.
Decoupling of the power supplies has to be performed by connecting decoupling diodes (so called O-ring diodes) to the secondary outputs. These diodes prevent mutual loading of the power supplies in case of a fault and thus guarantee continuous supply.
For the setup of redundant power supply systems, ABB offers two redundancy units, the CP-RUD (for output currents of up to 5 A) and the CP-A RU (for output currents of up to 40 A). The inputs of these units are connected to the terminals L+ and L- of the power supplies (many other manufacturers often consider L+ only). The loads are supplied directly from the outputs of the redundancy unit.

ring main unit in electrical power distribution
A standard piece of switchgear in distribution systems comprising of switches for switching power cable rings and of switches in series with fuses for the protection of distrbution transformers. 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.
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.
