dc power distribution recommended practices
Use these three tips to ensure a direct current (dc) power distribution project is successful.
1. Plan projects to include evaluation of alternatives, including dc systems. Opportunities may include the use of bulk rectifiers and dc buses for cooling fan and pump motors. Additionally, consider the dc voltage used by server equipment and providing a dc buses in the server aisle to feed this equipment. Connection of photovoltaic systems also typically includes a dc interface at less than 600 V.
2. Model the utility, generator, power converters, and loads to help develop interface standards, predict efficiency, validate the concept of operations, and identify key performance constraints, such as stability or harmonic distortion. Models can be used for energy management software development and testing. Many applications are suitable for this type of analysis.
3. Identify the power system equipment electrical interfaces, including harmonics, stability, and voltage requirements. Develop power distribution system architecture and interface standards appropriate for the project.

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.
