I recently obtained a big 3-phase transformer that could be useful if the
lights flicker too much with my single phase PSU! However, I need some help
in working out what DC voltage and current the transformer will produce.
The transformer has a primary with three separate windings coming out to
binding posts and so I assume that it can be linked either as a star or
delta configuration. Currently it's wired as delta.
There appear to be two separate secondaries. Each secondary has 4
connections - one winding marked A, B, C & N and the other A1, B1, C1 & N1.
Resistance measurements indicate that these are probably star configuration
(i.e. A-B = B-C = A-C = 200 ohms, A-N = B-N = C-N = 100 ohms). The
transformer is marked "1550 V RMS per phase, 0.35A RMS per phase".
Can anyone advise what sort of voltage and current I'd get out of this
transformer if I put a 3-phase bridge on the output of one of the windings?
What about combining the two windings? Does anyone know anything about an
Interphase Inductor or Interphase Transformer configuration for two 3-phase
windings?
Also, is there another place I should be asking these questions?
