Arc flash analytic software program
The DC Arc Flash Analytic (DCAFA V1.0) by ARCAD
The DC Arc Flash Analytic (DCAFA V1.0) by ARCAD is a software program for arc flash and shock hazard analysis in dc power systems, including but not limited to photovoltaics, battery banks, rectifiers, and telecommunications equipment. The program takes system voltage, available short circuit current, gap between electrodes, circuit time constant, electrode material, protective device type, and rating of a preset arc duration value, and determines incident energy released by arc flash, hazard risk category at working distance, and flash protection boundary. Among various key capabilities, the DCAFA V1.0 performs analysis using metric or imperial units, saves input configurations and calculation results for future reference or printing, and generates customized arc flash warning labels in electronic formats.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
