• Maintaining machines  - and customer relations  This year's EASA convention to emphasize on-site - and customer - service.  May is the first of three EA issues which will feature the 2005 convention of the Electrical Apparatus Service Association, to be held June 26-29 in Nashville, Tennessee. All three issues will be avidly read by everyone planning to attend the convention, as well as thousands of others with an interest in this key industry event.

• More to Music City than rhinestone glitter  Things to see and do in Nashville.

• In a small village, rebuilding transformers nationwide   Jerry's Electric handles thousands of all types from all across the continent. The company, founded in 1976 with one lone employee, today touts 65 acres, more than 50 employees and over 120,000 square feet of office, lab and repair facilities. Located among cornfields, four miles from the nearest town (Colman, South Dakota, population 500), the transformer service and sales company runs a coast-to-coast, border-to-border business with a sales force of five – we show how word of mouth and telephone marketing pays off for this operation.

• Service from a distance   Remote machine monitoring appears likely to be offered by independents. By David P. Tryling, EA Electronics Editor.

• Why we must be concerned with transformers    They are everywhere and - finally - U. S. efficiency standards may be on the way. A transformer is the most efficient A-C apparatus we have. Still, energy losses do occur. Our article, by EA Engineering Editor Richard Nailen, outlines how efficiency does matter, as well as what choices are available and what governs them. As the latest government regulations take effect, those who specify and purchase power transformers, and especially industrial commercial buyers, will welcome this timely article.

• Are three phases better than one? In some ways, but there may be problems. 

  Visit any engineering tips website, and you'll notice how frequently our article's title question is asked. Textbooks tell us much about the nature and measurement of current, voltage, and power relationships. Yet we find little information on the relative merits of the two systems. Our informative explanations and illustrations help contractors, system designers and power users understand the differences. By Richard L. Nailen, P.E., EA Engineering Editor

• Financing the unfinanceable   Expanding lines of credit at a time when credit is tight.
