Shocks

I had 700V DC up my arm through my own stupidity from this :-

Whats that? Some kind of rectifyer? I see it has 3 phases into it and some kind of 2-pole output, I assume this is DC given your statement.

It's actually a 12 pulse thyristor driven convertor, powering a 700kW DC motor. It has 2 x 3 phase inputs at 600A each fed from a phase shifting Tx. (One output star, one delta 30 degrees apart thus giving in effect 6 phases) Each phase is then output via the thyrisistors on their pos and neg halves of the cycle thus giving 12 pulses of 'DC' which is fairly smooth compared to, obviously, a 6 pulse.
As you can see there are two 'stacks' each giving DC output. These two outputs are combined in a reactor which is just out of picture to the right and is where I actually got the shock !

Take it from me, YOU DO NOT WANT A 415 belt. Got one a few years ago while commissioning a piece of switchgear, luckily i was not touching ground at the time and was stood on wooden steps, it still gives you a jolt(and does your watch no good either)

Why is it lucky you weren't touching ground ? You had already had the shock of greatest magnitude ?
The current did not flow through me, it only knocked me several feet sideways off the ladder.

If the current didn't flow through you then how did you get a 415V shock? To receive 415V shock you must came into contact with two phases and standing on wooden steps would make no difference in this case as the 415V shock would be between phase and not phase to earth. More detail please?
