Arc flash protection
Arc Guard TVOC-2 by ABB
Arc Guard TVOC-2 by ABB features upgrades and functions to provide arc flash protection, detecting faults in low- and medium-voltage switchgear and disconnecting the power provided to the arc within 30 to 50 milliseconds, preventing serious injury to personnel and damage to expensive equipment. Without the Arc Guard System, an arc flash will typically trip a circuit breaker in approximately one sec, enough time for the arc to destroy the switchgear and kill or seriously injure a person. TVOC-2 is now UL listed, and when installed along with ABB’s Emax circuit breakers, carries a functional safety rating of SIL-2. The SIL-2 certification confirms that the TVOC-2 has achieved the standard required to protect both humans and equipment.
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.
