# 5A-1 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 Table 5.2.2 from Chapter 5 is reproduced 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.

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.
