  • Finite element analysis of turbine generator rotor winding shorted turns

    Abstract Online magnetic flux monitoring via permanently installed air-gap flux probes is a well- established technology to determine the presence of shorted turns in a turbine generator rotor winding. Flux measurements are normally performed using flux probes installed in the machine air gap (on a stator wedge) and connected to portable or permanently installed instruments. In this ...

  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...


  • New Approach allows Subscribers to Reach the Summit of the Mountain of Information on Gas Turbine and Reciprocating Engine Technology

    The available information on combustion, flow control, treatment and environmental compliance for gas turbines and reciprocating engines is doubling every few years. It is now more challenging than climbing Mt. Everest to find the most current and relevant information. Rapid developments include zero liquid discharge (ZLD) technologies, repairable valves, high efficiency air inlet filters, ...

  • New methods for measuring the wind

    Although computer models of wind flow over terrain have improved dramatically in the past few years, there is still no substitute for data recorded at the site. So you want to build a wind farm. Good for you. With the global drive towards a low carbon economy, it is surely the right way to go for many individuals, companies and, indeed, Governments around the world. As information from the ...


  • Engineering Innovation into Driveline Design

    Introduction: thinking differently What is innovation? How can you harness innovation in practical ways to support your business goals? In the driveline industry and for engineering in general, “innovation” is often synonymous with the use of new or novel technologies/methods to achieve design and development goals - and ultimately deliver a higher quality product - in faster, ...

  • Desalination plant in Egypt runs on wind & sun

    Fortis Wind Energy (NL) and Juwi Renewable (DE) install a 100kW hybrid system in Egypt. Egypt, the land of the pyramids, is known to us for its ancient culture and the last year because of the uprisings for more democracy. Egypt is less known for its large population (83 million) lives along the Nile (only 5.5% of the surface). The rest of the country is desert. The River Nile runs into Egypt ...

  • Automated Oil Particle Analysis Helps Prevent Gearbox Failures

    The major issue for premature failure in wind turbine gearboxes is bearing failure, which leads to gearbox failure. A wind turbine gearbox will not survive if the oil is not clean and especially if the hard ferrous particles are not removed from ...

  • What rural Alaska can teach the world about renewable energy

    I flew into Unalakleet, Alaska, on a late fall day. With about 700 people, Unalakleet is large by rural Alaska standards and serves as a regional hub. The village is located on a sandy spit of land where a clear river meets the turbid water of the Bering Sea. Out the plane window the sun shone bright, glittering off the wind-tossed whitecaps of the sea. To the east, the rolling Nulato Hills, clad ...

  • Columbus, Georgia`s High-Efficiency, Low Cost, Digester-Gas-Fired Power Plant

    ABSTRACTGrowing concern over the cost of power and long-term availability of limited fossil fuel resources for the production of electricity have caused electrical utilities and governments to promote “green” or renewable power. Solar, wind, geothermal, biomass, biogas, and low-impact hydroelectricity are current acceptable green-power sources. Digester gas is a renewable, green energy resource ...

  • Opening the envelope on bearing vibration

    A sophisticated signal processing technique can help to pinpoint bearing failure at an early stage. Chris Hansford, Managing Director at Hansford Sensors, explains. Experienced operators can often tell if a machine is not working properly, on the basis that is does not ‘sound right’. The same principle can be applied – using modern electronics – to identify the exact cause ...

  • On energy, we`re finally walking the walk

    The United States has entered a new energy era, ending a century of rising carbon emissions. As the U.S. delegation prepares for the international climate negotiations in Copenhagen in December, it does so from a surprisingly strong position, one based on a dramatic 9 percent drop in U.S. carbon emissions over the past two years and the promise of further huge reductions. Prominent among these ...


  • Energy and the environment - A new look by an Old Hand

    I recently received an autographed copy of a new book from a friend that shone new light on an old problem - how to meet the world's energy needs without jeopardizing the environment. The book, entitled Renewable Energies with Energy Storage, was authored by Winston (Win) Stothert.  In it he tackles three very pressing and interconnected environmental problems - climate, energy and water. ...

  • PULSE smart start – a user’s experience

    Measuring on a Grounded Aeroplane   In the early days of PULSE, a team from Brüel & Kjær had the opportunity of performing a ground test on a Boeing 767. The left engine of the aeroplane had undergone a scheduled overhaul. The engine was reassembled and verified in a test cell. Everything seemed fine. The engine was mounted on the aeroplane and the aeroplane was ...
