MOTION CONTROL: A new white paper from Rockwell Automationhighlights the inherent dangers of arc flash, discusses the standards guiding arc-flash safety, and details the role that arc-resistant motor control centers (MCCs) play in helping to contain arc energy and reduce hazards.“Advances in Low Voltage MCC Technology Help Reduce Arc-Flash Hazards and Minimize Risks” discusses how changing industry standards are putting more focus on arc-flash risks, and highlights the key features and components of an effective arc-resistant MCC design. The paper stresses the importance of understanding the performance criteria that must be met before an MCC can be classified as an arc-resistant design.
According to the paper, an arc-resistant MCC is designed and built to provide a complete structural solution in accordance with defined industry standards. Arc-resistant equipment is designed to minimize arc-flash exposure by extinguishing the arc, controlling the spread of the arc or channeling the arc pressure and energy away from personnel.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
