Announcements:
Ask the experts! Every month, we ask a distinguished panel of experts for information about how to best solve your problems, challenges, and new engineering issues. Our M/E Roundtable discussion asks a variety of questions on a topic, and then has the experts provide details about how to handle the challenge. We’ll ask the experts your questions, and whenever appropriate, print them in the magazine and post them here.

1.The art of protecting electrical systems, part 15: calculating fault currents

4. Uptime Institute’s Design Charrette 2007 offers unexpected conclusions
The Design Charrette 2007, convened in October by the Uptime Institute, finds that it’s not so much technological breakthrough that will improve data center uptime as making better use of existing technologies.

5. Webcast on Selective Coordination for Emergency and Legally Required Power Systems
Selective coordination is a goal in any power distribution system design. Achieving selective coordination in a power distribution system served by two power sources with disparate impedances and capabilities presents a real challenge. Join us for a Webcast on Friday, Feb. 8, 2008 11am PST/1pm CST/2pm EST.
