I'm guessing it's probably mostly cost and size. A 14.4 pig=a couple hundred
bucks and around 250-300lb. A 69kv pig/padmount= a couple thousand if you
can find one and 1500+ lbs for same kva (pads of that voltage don't get
smaller than 112.5 unless it's a pt type, $3500 for a used one in that
voltage class). Same problem with the cap. Most people don't have a
forklift/crane in their garage. Overall, higher voltage makes a more
efficient coil. Question is, is 10x the cost/weight worth 10-20%
improvement? Though an x-ray transformer from ebay and a few hundred (or
more) mmc caps would probably be the cheapest way to go...
