The load break switch panel will be provided with a. In the medium voltage switchgear type Xiria there are no.

Susol RMU is enable to install on medium voltage distribution network and mainly used Metal enclosed unit for Indoor installation and type tested. Fully automatic interlocking system. Clear indication of operation status via mimic diagram on front panel.

Although we can say that the ring network is supplied just by a single circuit, it is similar to other two-way power supplies which enhances the reliability of power distribution throughout the substation.

To make it short: Once 11kv rmu panel file type right trunk fails to supply, the entire system can tiletype depend on the medium voltage supply provided by the left trunk.


Tiletype same goes when the left trunk fails to do its job.

It is also safer. When one section suffers damage, you can easily disconnect it from the system and conduct a repair while the rest of its components continues to supply the ring. Ring Main Unit Types Based on Protection There are basically three classifications of ring main unit based on their shielding components: Fuse type 11kv rmu panel file type type Disconnection type While they are almost the same in terms of protection capabilities, they can vary with the cost they can incur to the consumers and also the load substation they can handle.

Fuse type ring main units are said to be the most cost-efficient type of feeders that can provide overcurrent and earth fault protection to distribution systems running with up to kVA transformer. Fuse type RMUs are propelled by trip coils attached from the protection current transformer. Thus, whenever a fault happens, it can be easily broken and the fault current will be shifted towards the trip coil, slipping the circuit breaker off.

Sometimes, consumers may think that they can use fuse type ring main units to limit the overload 11kv rmu panel file type of their transformers, but this may lead to a wrong way.

Fuse type ring main units are designed to be used only for fault protection. Another type of ring main unit makes use of a self-powered breaker relay protection, which is also designed to protect the transformer or the downstream network from fault currents. Some breaker type ring main unit manufacturers include the following features: Thermal load protection Optional password for more complete and assured control of devices Added tripping functionality and Modbus protocol support Recording and measurement of fault currents Breaker type RMUs can also support a wide range of transformers and can prop up with diverse industrial applications.


In North American distribution practice, often the equivalent of 11kv rmu panel file type ring main unit is built into a pad-mounted transformer which integrates switches and transformer into a single cabinet.

Categories[ edit ] Ring main units can be characterized by their type of insulation11kv rmu panel file typeoil or gas.

It includes 11kv rmu panel file type one unit two switches that can connect the load to either or both main conductors, and a fusible switch or circuit breaker and switch that feed a distribution transformer. Ring main cables enter and pnael the cabinet.


Categories[ edit ] Ring main units can be characterized by their type of insulationairoil or gas. The switch used to isolate the transformer can be a fusible switch, or may be a circuit breaker using vacuum or gas-insulated interrupters.
