The IET is carrying out some important updates between 17-30 April and all of our websites will be view only. For more information, read this Announcement
Am I correct in simplifying a ring circuit like this in theory? Assuming the loads are the same 1ohms and the distance between each load is the same as well.
I imagine the red lines represent low resistance current paths that are in fact made of insulated metal wire and are much longer , and far more convoluted, than on the diagram, and A denotes current in amps flowing in a line adjacent to the letter. 
There is the complication that if that is true it depicts a centre fed radial, not a ring, and the layout and choice of letters is unusual, but not impenetrable.
I'd be the first to agree it is not a standard schematic diagram to BS3939 nor the ISO standard for that matter.
