Transformers, which are prone to leaking, are an excellent example of where using the right materials and techniques can quickly reduce cleanup costs and potential environmental damage from a fluid leak. Transformer leaks are most commonly caused by degrading cork gaskets or holes in the radiator fins or the steel tank. Often these leaks are slow drips, but occasionally a catastrophic leak will occur, spilling hundreds of gallons of mineral oil into the environment and causing the transformer to short-circuit, causing further health and safety concerns. These dangers, coupled with transformers’ isolated locations, make inspection, repair, and maintenance a major challenge.

Oil skimmers are very effective in removing oil from wastewater before discharge but are also perhaps the most efficient and economical approach.

Baumer introduced the new MOR 90 and MOR 105 magnetic incremental encoders for improved speed and position control on electric motors, drives, gearboxes, and conveyors. Measuring just 14 mm thick, these extremely thin, flange-style encoders are virtually imperceptible when positioned between the motor and the gearbox and have little effect on the overall size of […]

Ashcroft A-Series pressure switches are designed for tough OEM and industrial applications that require a durable, high-quality miniature switch. Available with explosion-proof and watertight enclosures, the pressure switch features a refined piston actuator that can be ranged up to 2,000 psi while enduring a working pressure of 5,000 psi. Small dimensions, a choice of connections, […]

Racine Vortex released its RNS Series (Insertion) and RWS Series (Wafer) Vortex Steam Flow Meters to measure noncondensing steam and saturated process steam at pressures up to 150 psi for applications such as boiler monitoring. Both meters have no moving parts and are loop-powered devices with standard HART communication for ease of field programming and […]

News items of interest to power generation professionals.

After years of decline amid rising prices and fears of scarcity, natural gas as a power-generating fuel is on a rebound in the U.S., driven by new finds in Texas and the Mid-Atlantic states. These news stories highlight the trend.

Is management a science? An enormous intellectual construct developed over the past century—by business schools, consultancies, and major staff components of business firms and government agencies—is dedicated to that proposition.

Natural gas has reemerged as the choice for new electric generation, according to the North American Electric Reliability Corp. Does this raise new reliability issues?
