# 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.
