Thames Water Ring Main was created in 1993.
how, in simple terms, would you describe a ring main (Specifically medium voltage)
how are devices connected to a domestic ring main
A ring-main unit is a piece of switchgear used on high-voltage distribution ring-main systems (e.g. in the UK at 11 kV). Essentially, it's three switches incorporated into one device used to connect a transformer to a high-voltage ring main. It allows the transformer to be connected/disconnected to the ring main and it also allows the ring main to be 'broken'. Each of the switches has three positions: open, closed, or earthed (grounded); the earth position allows the transformer or either (or both) halves of the ring main to be earthed when maintenance is required.

It consists of three load-breaking switches, each with three positions: 'on', 'off', and 'earth'. They enable the transformer to be connected/disconnected to the ring; the ring to be 'broken'; or the transformer to be connected to either half of the broken ring. The 'earth' positions allow the transformer's secondary to be earthed, or either half of the (broken) ring to be earthed.
BS 7671:2008, Requirements for Electrical Installations, specifies that any number of socket outlets can be added to a final ring circuit (ring main), but the ring main must not supply a floor area exceeding 100 square metres.
No. Jupiter has a faint ring system composed of three main segments. There is also some suspicion that there is a fourth ring segment. See the Related Link below for more information.
Jupiter is known to have 4 sets of rings: the halo ring, the main ring, the Amalthea gossamer ring, and the Thebe gossamer ring.
You ring them and ask to renew... or you go in and re-new.
An 'RMU' is a 'ring-main unit', a type of switchgear used to connect distribution transformers to an underground, secondary-distribution (11 kV in the UK), cable ring-main system. It enables the transformer to be disconnected from the ring main, and it also enables the ring main itself to be 'split' where the RMU is installed. Each of the three switches within an RMU usually incorporates an 'earth' (ground) position, which will enable either the transformer itself, or the ring main to be earthed for safety reasons before any maintenance work can proceed.
