Enveloping is a tool that can give more information about the life and health of important plant assets. It is primarily used for early detection of faults in rolling element bearings and gearboxes. Enveloped acceleration is an especially valuable parameter to trend, as the progression of machine condition can be evaluated. Armed with good information and assisted by service experts, plant engineers can be confident in the proper operation and management of the important assets in their care.

Today's electricians are often found working in applications outside the realm of what is traditionally considered "electrical." Through new programs sponsored by the IBEW-JATC training schools and others, the skill sets of the electrical union workforce have broadened to include automation and controls.

Have you ever wondered why a motor manufacturer would state that many of their 60-Hz motors will operate on 50-Hz power as long as you reduce the nameplate voltage by 1/6?

Production, distribution and refining applications in the oil and gas industry rely heavily on motor-driven pumps and pumping systems. Keeping electric motors driving critical operations at peak performance is vital to ensure maximum profitability.

A recent marketing survey found that 84.0 percent of satisfied customers would "jump ship" for a better deal if an opportunity arose. With markets becoming increasingly globalized, customer retention has become a critical part of business strategy. Companies need to ask themselves: What reason can I give this customer to stay, even if my competitor offers a cheaper price? The keys lie in keeping customers loyal to brands and products and ensuring a consistently outstanding customer experience.

The small town of Groin, Mo., has an excellent source of water. The water board says its wells and distribution system are coasting along at about half the maximum capacity. Since demand is growing at less than 2 percent per year, it would be reasonable to assume the current system is more than adequate for many years.

Starting can have a significant effect on the life of the winding insulation of an AC motor.

In recent years, adjustable frequency AC drives have become increasingly popular as they provide an efficient, direct method of controlling the speed of the most rugged and reliable of prime movers, the squirrel cage motor. They provide a spectrum of benefits for a broad range of applications.

A crucial triumvirate for improving the bottom line. pump system optimization, pump efficiency

Frequency Hopping Spread Spectrum (FHSS) radio was invented during World War II by the military for communicating information and strategic plans to allied forces in a way that would counter enemy efforts to "jam" or intercept traditional radio communication frequencies.

There are several ways to control two identical, parallel pumps operating under variable frequency control in pumping applications.

The service department of a variable frequency drives manufacturer frequently sees the following scenario: A frustrated user calls with what he perceives to be a defective piece of equipment. As the technician begins probing for information, the user's frustration boils over, often with an exclamation along the lines of "what a piece of junk!" As the service technician asks the pertinent questions, the exasperated user relays the details of a drive that is continually tripping on a fault until the user is at the end of his rope, not knowing what to do.

Lift stations can be difficult and costly to monitor, especially when the stations are located in remote areas.

Traditionally, the primary use of drives has been in applications such as powering pumps, fans and conveyors. While they will continue to be used in these applications, today's end-users have a different approach from that of a decade ago.

Wireless technology has significantly impacted business worldwide. It enables a greater degree of connectivity among devices for enhanced monitoring and utilization of existing assets. It has also led to the development of new applications that improve productivity, uptime and overall business performance.

Economic pressures to minimize production downtime and improve operating efficiency are increasing the emphasis to accomplish on-site problem detection, analysis, and resolution as fast as possible. These requirements place a great deal of pressure on maintenance personnel to have all the right tools readily available in one place.

In the early days of adjustable frequency drive (AFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars and aluminum foil. Because AFDs improved performance and lowered maintenance costs, they replaced motor generator sets and DC drives. When the energy crises occurred in the early 1970s, saving energy became a critical goal, and the use of AFDs quickly spreadpump efficiency, into large pump applications and eventually into HVAC fan systems. pump efficiency, pump system optimization

While scheduled downtime is different from unscheduled, both can take away from a company.

Balancing is essential for minimizing vibration, increasing bearing life and minimizing downtime and repair costs. Follow the guidelines from these standards to balance centrifugal pumps properly.

In the foothills of the Andes, among the sprawling vineyards of picturesque Mendoza, Argentina, stands an innocuous equipment cabinet located by the side of an infrequently used mountain pass. The cabinet's superficial surface rust belies its importance as one of the most significant technological developments in modern day corrosion prevention. The cubicle, battered from years of an abrasive cocktail of arid Patagonian winds and coarse earth, hides the cradle of a revolutionary approach to cathodic protection. The equipment within the cabinet resulted in an entirely new range of products.
