Making a 3-Phase Transformer with 2 Single-Phase Transformers

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of constructing a three-phase transformer using only two single-phase transformers, exploring various configurations and theoretical implications.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that while three single-phase transformers can create a three-phase transformer, the possibility of achieving this with only two transformers is in question.
  • Another participant mentions the "High Leg Open Delta" configuration as a method to utilize two transformers for three-phase output.
  • A different participant introduces the Scott-T configuration, stating it can convert two-phase power into three-phase power, clarifying that "two-phase" refers to a specific 90-degree phase difference and not split phase.

Areas of Agreement / Disagreement

Participants present multiple competing views on the configurations possible with two transformers, indicating that the discussion remains unresolved regarding the best approach.

Contextual Notes

There are assumptions about the definitions of phase configurations, and the discussion does not resolve the mathematical or practical implications of the proposed transformer setups.

Well we can make a three-phase transformer using THREE single-phase transformers, but is it possible to make one, using only TWO single-phase transformers?

Nice. Thank you.
 
A Scott-T configuration will make 3 phase out of 2 phase. By 2 phase I mean actual real 90 degree out of phase 2 phase and NOT split phase.
