   Thanks for taking the time to reply.  I've got one of the "bible" EE   
   handbooks, McGraw-Hill's "Standard Handbook for Electrical Engineers"   
   that has extensive info on AC power distribution components   
   (distribution transformers, oil/air circuit breakers, reclosers,   
   cutouts, PF correction capacitors) but doesn't discuss methods for   
   determining capacitor bank optimum location along a distribution line.   
      
   Also, my online searches revealed no equipment that can directly measure   
   power factor or current lag at an arbitrary location along an MV   
   distribution line.  Would be kind of dangerous I would think.  Sincerely,
