What are the requirements for a ring main unit?

The Ring Main Unit itself must comply with the requirements of AS 62271.200 Annex A.2, Accessibility Type AFL. Operators of the Equipment must be protected against the effects of an arcing fault in any of the MV compartment at all times, including while carrying out maintenance work on other compartments.

What is a ring main unit?

Though RMUs are integral to ring network configurations, their utility extends far beyond. Load switch-based high-voltage switchgear has become increasingly prevalent across non-ring distribution systems; hence, the term “Ring Main Unit” has become widely applied to any high-voltage cabinet that predominantly utilizes load switches.

What is a ring main unit (RMU)?

The Ring Main Unit (RMU) gets its name from each switchgear in a distribution branch, part of its busbar loop, creating an interlinked ring-shaped structure.

How do I design a 4 wire energy metering unit?

Energy metering units (4-wire) must be suitable for direct connection to adjacent extensible switch-disconnectors and fuse-switches or circuit breaker RMUs. The design must include a sealed and lockable marshalling enclosure that may be safely accessed from the front of the metering unit, with the main busbars live.

What are ring main cables used for?

Ring main cables enter and leave the cabinet. This type of switchgear is used for medium-voltage power distribution, from 7200 volts to about 36000 volts. The ring main unit was introduced in the United Kingdom and is now widely used in other countries.

What are the requirements for a metering unit?
