What is ring main unit (RMU)?
RMU, Ring Main Unit, is a medium voltage switchgear, consisting several electrical components, Load Break Switch, Circuit Breaker, Fuse, Surge Arrester, Instrument Transformer, Protection Relay, etc.
Can RMU be installed inside a prefabricated substation?
Space Constraints In PV, BESS and wind power applications, RMU is most used inside the prefabricated substation with a container or similar enclosure. Since transformers also need to be installed, the installation space left for RMU is quite limited. If the size of the RMU is too large, it is not easy to install.
Why is maintenance important in New energy applications?
In new energy applications, the cost per kWh is an important factor affecting customer revenue. As a result, equipment requiring maintenance will increase operation and maintenance costs and reduce revenue. Especially many plants are located in remote areas, which further exacerbates this issue. 5. Installation Convenience and Operational Safety
