5A.1 INTRODUCTION

This appendix provides supplementary results from the engineering analysis, including

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

supplementary 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

This appendix reproduces Table 5.2.2 from Chapter 5 as Table 5A.1 below for reference,

and provides a summary of the engineering design lines and the specifications of each of the

representative units.

* PC means Product Class (see Chapter 3 of the TSD). The Department calculated the analytical results for PC5, PC7,

and PC9 based on the results for their three-phase counterparts. The Department did not select any representative

units from the single-phase, medium-voltage product classes (PC5, PC7, and PC9) because of their low sales volume.
