Transco makes their NSTs in "normal" power factor, and "high" power factor versions. VA ratings are the same, but HPF transformers cost more. What's the difference? I've been running a Transco outdoor-type NST rated 15kv-at-30ma, "normal" power factor. It seems to work fine. Greg Freezing in East Anglia
