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.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material thats ideal for storing energy and creating a powerful supercapacitor.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
