An RMU is a medium voltage cabinet containing input and output cable compartments. It isolates these individual compartments with single breakers connected to cables that go out to transformers. Each compartment has load breakers and protective fuses installed. RMU cabinets come standard in two, four, and six-compartment setups.
Each cabinet will contain different types of switches that can have varying purposes. For example, one switch may feed a distribution transformer while another may connect with a load. These highly compact power distribution units are utilized for medium-voltage power situations. RMUs can be constructed for various configurations, with the 24 kV distribution network being the most commonly used today. It's important to realize that each cabinet or unit is a completely sealed system.
Each RMU switchgear has three main functions. It controls the circuit to switch functions, isolates faulty equipment from the remaining circuit, and protects the circuit from short-circuit faults, the ground-fault current, as well as overloads.
Thanks to the technology inside of RMUs, they go a long way in reducing power outages and helping you to maintain a constant supply of power.
RMUs are ideal for helping you to manage the various challenges of power distribution. These all-in-one solutions are safe switchgears that are simple to install for various voltages.
They are constructed to withstand harsh environmental conditions and can be placed both indoors and outdoors. These RMU systems offer enhanced protection against overload current fault currents, phase-to-phase fault currents, and ground contact currents.
With virtually no maintenance required, these compact units last an average of 20 years. Integrated with internal self-testing features that allow you to know exactly when something is amiss during the commissioning stage, these RMUs ensure optimal quality protection. With their equipped smart electronics and communications capabilities, RMUs are far superior to traditional RMUs.
RMUs are very simple to integrate with any distribution management system and make Smart Grid solutions a breeze for all operators. Even better, you can enjoy grid connectivity without having to worry about your level of data security. RMUs are both cost and time-effective, which are highly prized traits in the 21st century.
RMUs are utilized in a number of underground cable transmission network applications where medium voltage power distribution is necessary. They're extremely in demand for those industries that require a continuous and reliable power supply and can afford the higher upfront cost of the unit.
These include residential complexes, business centers, hospitals, resorts, airports, metros, solar power plants, wind power plants, small secondary substations, and so much more. They're ideal for minimizing downtime, as any interruption in the power supply can be instantaneously replaced with manual or automatic switching.
