I dpn't work on this side of power, so I'm not very good at eyeballing the rating of these xfmrs, and as has been mentioned in here before the variation in design parameters can make a visual "guess-timate" difficult anyway.
Yes, the primary is 11kV, secondary 240V. This xfmr is feeding one house, and residential services these days are usually 100A, so 25kVA or thereabouts would be reasonable.
I think I see what you mean about the primary/secondary cabling. It's complicated by the fact that this being a pole where each run is terminated and tensioned there are the jumpers across the pole. The jumper on one side of the primary line is supported by an insulator above the cross arm while the other jumper is run belowp it. From the angle of the picture, it could appear as though that jumper is heading toward one of the secondary lines.
