If you look back here, you will see that even the V2 equipment installed varies from unit to unit. Definitely bottom of the scrap heap.
I still wonder why they did 6 V2 vs 4 V3. V2 is 450 kw total for 3 cabinets, V3 is around 400kw total per cabinet. If they have a 500kva tranformer, they could have even done 8 V3. Anyone know the transformer size?
