I will let this run a bit then tell you where it is and who posted if if no one guesses, though I suspect at least one forum member will recognise it straightaway.


If I read it correctly it does say it has a six phase supply.

    Mike, you are right, Kempton Park rectifiers give 200 v dc at 200 amps.


    To reduce the 3rd harmonic primary currents the two star points are connected via a centre tapped auto transformer, the neutral taken from the centre tap.  This has the effect of "flattening" the peaks and increasing the conduction time of each anode, and also reducing the ripple.
