This book provides transformer purchasers with the knowledge and tools to help them decide what product size and efficiency ratings are best for them.

The decision whether to purchase a low-cost, inefficient transformer or a more expensive, energy efficient model is primarily an economic one. In addition, energy efficient transformers reduce energy consumption and consequently cut the generation of electrical energy and greenhouse gas emissions. Before deciding which version to purchase, weigh the capital cost of high- and low-efficiency transformers against the expense of their losses over time.

There are many books about transformers, but none is dedicated solely to the efficient use of the products. This book helps users of transformers save money as well as energy. Chapter 2, "Transformer Characteristics," provides the necessary fundamentals on theory, construction, operation, and energy consumption. Transformer losses and how to reduce them are the subject of Chapter 3, "Transformer Efficiency." Later chapters provide information on new technology, such as amorphous and laser-etched metals, and insights into specially designed transformers such as K-factor.

A diskette is included with the book containing the EPA's Distribution Transformer Cost Evaluation Model (DTCEM), ver 1.1. This program helps engineers perform the complex economic analyses needed to accurately determine the cost effectiveness and emission reduction potential of high efficiency transformers. It also provides the information necessary for facilities to weigh purchases of high efficiency distribution transformers against competing resource options.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
