So here's how to phase them correctly:

connect the primaries in parallel of 2 transformer, and connect a (well 
insulated) to the output bushing of one of the transformers.  Try to draw 
an arc from the same position bushing of the other transformer.  If you can 
draw a normal arc, then reverse the primary connections of one of the 
transformers.  Repeat this with the 3rd transformer, but if you need to 
change the primary connections, change the connections on the 3rd NST.
Now just connect all the HV bushings on the one side of the transformers, 
and the 3 HV bushing on the other side of the transformer, and you have all 
3 in parallel, now 6kv -at- 90 mA.  Hope that makes sense to you!
