Troubleshooting 4 to 20 mA (milliamp) process control systems without breaking the loop using Fluke 773 Milliamp Process Clamp Meter
“Cogeneration” captures heat from energy-intensive industrial processes and puts it back to work—to make steam that drives a turbine generator or that heats other parts of the facility, for example. Heat recovery can increase energy efficiency by 30 percent or more. Cogeneration has garnered a lot of attention as a result, and sophisticated, almost turnkey cogeneration solutions are now available in a range of sizes. Even the most sophisticated cogeneration system, however, is an electromechanical system that requires regular maintenance for reliable operation at peak efficiency.
Since a small increase in current flow to a motor produces a proportionately larger amount of heat, motor amperage exceeding nameplate values should be carefully investigated as a possible cause. These overload trips, though often caused by motor loading issues, can also indicate bearing failure, insulation breakdown or voltage unbalance.
You could call this a factory, but you've never seen a plant like this before. The "manufacturing" process here relies on "shots" of laser energy focused on a target the size of a BB. The product: a nuclear reaction six times hotter than the core of the sun . . . and a growing understanding of fusion reactions that could one day free the planet from dependence on dwindling fossil fuels.
