    Very nice, thanks @Windadct -- nice touch on using fiberoptics for isolating the control signals. :smile:

    Aha moments (or weekends) are one of the best parts of Engineering, IMO. :biggrin:

    In in this MV cellular set up - each cell effectively has it's own ground, and has to generate it's own control power, lots of small innovations - and to think this was not that long ago (90's). Every cell's superstructure has to be isolated from the next, but then also you need balancing system - like a voltage divider, so that no one cell "floats" too far away from the others. Isolation of structures in MV systems is "fun".. haha
