Surge protective device
Finalist in Electrical Distribution in Consulting-Specifying Engineer's 2011 Product of the Year competition
The Liebert SH Hybrid Series surge protective device from Emerson Network Power is a hybrid product with a coordinated multistage system of suppression. It uses a transitional method that includes a silicone avalanche diode module with tight clamping and rapid response. There is also a secondary metal oxide varistor module for high-energy capacity. This is made possible with an impedance-matching network with controlled copper geometries. The series offers component-level monitoring, including neutral to ground. It has a sand-packed silver fuse network that is UL-rated at 200 kA interrupting capacity. All of the product’s surge suppression components are computer-tested.
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.
