New ABB inverter to feed photovoltaic power into the grid
ABB's first solar inverter, the PVS800 is designed to connect photovoltaic arrays to medium- or low-voltage grids via transformers and switchgear.
Photovoltaic plants, in which solar energy is collectedby light-sensitive panels and converted directly into electricity, rely oninverters to convert the direct current produced by the cells into alternatingcurrent, which is needed for electricity distribution. ABB's new product, thecentral inverter, PVS800, feeds solar power into medium- or low-voltage grids viatransformers and switchgear.
Available in power ratings of between 100 and 500kW, the new inverter can be used in both industrial-scale photovoltaic power plantsand for medium-sized power plants installed on the roofs of commercial orindustrial buildings.
The new solar inverters are based on technology
developed by ABB for use in variable-speed drives (devices that control the
flow of power to electrical equipment, tailoring performance to the needs of
the task in hand). The new inverters are also supported by ABB's maintenance
and service offering.

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.
