“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.

“Let's just oversize the motor and we can run it lightly loaded—that will save us some money and be easier on the motor.” This is a false belief among some who select and install motors. Properly sizing motors for a given load results in driving loads more efficiently, saving energy, and saving dollars. Motors typically are most efficient when they are 90 % to 95 % loaded. Just because a motor says “25 Hp” on the nameplate does not mean the motor is producing twenty-five horsepower as it operates.Clamp meter readings: Problems and Solutions

Infrared thermography provides the capability to help detect subtle problems before they result in failures. In industrial settings some equipment problems can be spotted through unusual vibration or sounds, but many other problems do not present such obvious symptoms. Many electrical problems can be detected by their thermal patterns, which, if not identified, could either lead to equipment failure or a more serious electrical hazard. Moisture problems in ceilings and walls can be very difficult...

Infrared cameras are ideal for finding apparent temperature differences between components or materials that can point to a potential problem.

Sometimes vibration in industrial equipment is a symptom or even a cause of trouble; other times, it is part of normal machine operation.

The most popular reason for paralleling conductors is to provide higher ampacity than a single conductor can provide. "In a typical building design, the largest conductors are usually 500 kcmil or 600 kcmil". "And many electrical contractors will actually object to 600 kcmil. If ampacity above 400 A is necessary, using parallel conductors is the only reasonable solution.

Electrical safety requirements for using digital multimeters per OSHA and NFPA 70E

Your Low-Cost Electrical Audit: What to Test, and How Energy conservation programs don't have to entail major investments in new equipment and systems. Often facilities maintenance teams and/or outside contractors can achieve significant savings in electric power used and billed just by testing and tuning up the systems they have today. With just operational changes or different maintenance practices, they can find savings to strengthen the bottom line, reinvest for even greater savings, or both.

Five years ago, with the move to highefficiency equipment, Fluke began receiving trouble calls from service techs. The calls came post-installation, and they weren't about the new equipment—they were about other parts of the system that were now operating erratically, if at all.

ROI for industrial energy efficiency programs. How manufacturing plants can identify energy waste, save on utilities, and industrial energy costs.

Kiln-drying wood is a 24/7 process. That is why Zena Forest Products mill owner Ben Deumling was so anxious to ensure that the new dry kiln he was setting up was as energy-efficient as possible. Deumling started with a 24-foot kiln built from a repurposed refrigerated shipping container, and installed a set of three ¼-horsepower single-phase fans to move the warm air over the wood.

Power reliability for facility managers (bottom line): top issues; adds, moves, changes; electrical and electronic loads; emergency power; older facilities

The electrical power issues that most frequently affect industrial plants include voltage sags and swells, harmonics, transients, and voltage and current unbalance. The proper tools to correct these issues include knowledge and electrical test instruments ideally suited for each task.

Critical systems run smoothly with regular maintenance and reliable tools Everybody knows that consistent, dependable electrical power is critical to any plant's function. But perhaps even more critical is a reliable uninterruptible power supply (UPS) system. UPS systems are the silent partners that just sit and wait until there's a break in power. At that point, the UPS system is the most important system in the plant. It has to be ready to spring into action in milliseconds to keeps things running for anywhere from seconds to hours.

The effective date of the latest version (the 2011 edition) of NFPA 70: National Electric Code” (NEC) was August 25, 2010. It was published in September 2010.
