The only feasible context would be a case where someone is on a highleg and happened to need to run a single phase motor. The only question left, some experimentation required, is whether there is an advantage to starting with a highleg instead of a start capacitor. | |

| Sep 26, 2021 at 10:02 | comment | added | vu2nan | Andrew Graham, To which terminals of the high-leg delta transformer would the motor be connected? A schematic would help understand your concept. | |
| Sep 25, 2021 at 22:52 | comment | added | Andrew Graham | The highleg voltage is 90deg out of phase with the 120v. If the reference phase is B to A with B being the highleg and the center tap being across A and C, we would expect to see 120v at 120deg and 208v at 30deg | |
