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
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
