-Useful for Utility Power connection to convert 3ø to 1ø and allow full use of all three phases.
+Useful for Utility Power connection to convert 3ø (120 degree phase angle, 3 wire) to 2ø (90 degree phase angle, 3 or 4 wire) and allow full use of all three phases.
+Scott T-Transformers can be built to transform voltage as well as polyphase (such as 480v delta to 120/240v), but that does not appear to be as useful in most applications we consider here.
+For further background.
-Probably not possible to do percentage tap adjustments for low voltage since percentage taps are required for the phase relationships.

     * Scott T Transformer is built with two single phase transformers of equal power rating. The MAIN and TEASER sections can be enclosed in a floor mount enclosure with MAIN on the bottom and TEASER on top with a connecting jumper cable. They can also be placed side by side in separate enclosures.L/C Magnetics can custom build Scott T Transformers with power rating from 1 KVA to 500 KVA.
