Power control systems
Russelectric on-site power control systems are equipped with dual programmable logic controls (PLCs) for automatic generator set starting and stopping, status and alarm annunciation, synchronizing, and priority load control.
All Russelectric on-site power control systems are equipped with dual programmable logic controls (PLCs) for automatic generator set starting and stopping, status and alarm annunciation, synchronizing, and priority load control. A primary PLC system operation with a backup PLC running the same program as the primary. If the primary PLC fails, the backup PLC assumes operational control. If both PLCs were to fail, a manual control system allows operating personnel to synchronize and parallel the generators onto the bus, as well as to add and shed load. This built-in redundancy is included in all Russelectric on-site power control systems. The instruments and other devices that facilitate manual operation (including generator main bus volt meter, frequency meter, and synchroscope) are mounted on a hinged panel that can be specified to swing either left or right for easy viewing from adjacent control cubicles during manual operation. Russelectric custom designs and builds power control and synchronizing switchgear systems in low- and medium-voltage ratings for single- and multi-unit on-site power generators.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
