APPENDIX 5A. ADDITIONAL ENGINEERING ANALYSIS RESULTS

5A.1 INTRODUCTION

This appendix provides additional results from the engineering analysis, including 

information about the distributions by price for each of the representative units analyzed. These 

results are based on the reference case engineering analysis, not the symmetric core or 

supplementary aluminum design sets. These results include the following:

1. No-load (core) losses versus manufacturer’s selling price

2. Load-losses (coil) versus manufacturer’s selling price

3. Transformer weight versus efficiency

Table 5A.1 is reproduced from chapter 5 for reference, and provides a summary of the 

engineering design lines and the specifications of each of the representative units.

* EC means equipment class (see Chapter 3 of the TSD). DOE did not select any representative units from the 

single-phase, medium-voltage equipment classes (EC5, EC7 and EC9), but calculated the analytical results for EC5, 

EC7, and EC9 based on the results for their three-phase counterparts.
