  • From Drought To Flooding: California Struggles With Turnaround

    In a drastic about-face, California has gone from historically desperate drought conditions to an inundation of water that has brought its own set of problems.  In one indicator of the dramatic difference, snowpack on the Sierra mountains recently measured 135 percent of its seasonal average. “We haven’t seen an event of this magnitude in at least a decade,” Mike ...

  • Secondary Oil Containment at US Army Corps of Engineers - Big Bend Dam - Case Study

    Big Bend Dam takes its name from the unique bend in the Missouri River seven miles upstream from the dam. Construction of the dam began in 1959 and the embankment was completed in July 1963. Big Bend dam is 95 feet (29 m) high and 10,570 feet (3,220 m) in length. Power generation began at the facility in 1964 and the entire complex was completed by 1966. The hydroelectric plant generates ...

  • Using Electromagnetic induction to characterize soils - Case Study

    Electrical conductivity measurements have been used for years to determine salinity and moisture in soils. Probes were inserted directly into the soil to determine how well the soil conducted an applied current. This process was slow and labor-intensive and was usually reserved for scientific studies. A more recent technique for measuring conductivity is electromagnetic induction (EM), a ...

  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...

  • What Is Zero Liquid Discharge and How Does It Work?

    Not every industrial facility that produces wastewater will require zero liquid discharge (ZLD). It is usually looked to as a last resort because it can be a complex process that requires a high initial investment. If a facility is located on a site that has severe water scarcity issues and/or astronomical discharge fees, it might be ...

  • Does your facility need Zero Liquid Discharge Technology?

    If your industrial facility discharges its waste into deep wells, streams, sewers to publicly owned treatment works (POTWs), and/or other waterways, it is likely there are some types of regulations on discharging the waste. With an increasing push toward environmental protection, many industrial facilities and effluent regulators are strengthening strategies to reduce industrial process waste. ...

  • Hidden failures in electric power systems

    Hidden failures in equipment are those failures which occur at random and that do not lead to any discernible change in the state of the network and, therefore, remain undetected. Although hidden failures can occur in any equipment, the hidden failures in protective equipment have attracted a good deal of attention in recent years. Admittedly these failures are rare but, when the power system is ...

  • Harmonic assessment of electrical power systems

    Advances in semiconductor technology have resulted in an escalation in the numbers and power ratings of non-linear loads connected to the power system. At all voltage levels, equipment is being installed which generates harmonics. At transmission levels, FACTS devices are being installed for controlling power flow, HVDC links are used to transfer real power between AC systems and large industries ...

  • Agents controlling the electric power infrastructure

    The electric power grid is evolving from a centrally controlled grid with only a handful of regulated monopolies to an open, liberalised electricity market. In addition, more and more small-scale dispersed generators are deployed in distribution nets. This puts extra stress on the power grid, in an era when electricity is one of the most important commodities for economic, industrial and everyday ...

  • Power management policies and control of hybrid electric vehicle

    With increasing concern over the environment and ever-stringent emission regulations, the use of hybrid electric vehicle (HEV) is being investigated as an alternative form of transportation. A hybrid vehicle combines the advantages of an electric drive and an internal combustion engine. This paper proposes the necessary hardware and software needed for an effective control of the electrical part ...

  • Online condition monitoring of electrical power system imbalance

    Symmetrical components are of great importance in many applications in electrical power systems, such as power protection and condition monitoring. This paper presents a computer-based algorithm for online symmetrical components estimation. The proposed algorithm uses the samples of the phase variables (currents or voltages) to estimate the magnitude and phase angle of each phase phasor at each ...

  • Benefits of the Best Pressure Washers Powered By Electricity

    Ask any expert about the best pressure washers and they are likely to mention the electric powered versions. Since they run on electricity, the electric-powered ones are highly versatile and ideal for use in almost all settings with reliable electrical supply. The cleaning efficiency of the best pressure washers is measured in terms of their pressure in psi (pounds per square inch) and flow ...

  • Electric vehicles powering communities through natural disasters

    Mass power outages and blackouts have always been of great concern during and after natural disasters. In addition to the devastation that can occur from flooding, collapsed buildings, and disruptions to basic infrastructure, the absence of electricity can shut down basic communications systems, adding to the anxieties of those most critically affected. While much discussion revolves around what ...

  • Assessing the impact of interdependencies in electric power systems

    Electric power systems (EPS) greatly support our daily activities and are therefore among the most prominent critical infrastructures that need to be reliable and resilient in providing their services. They are rather complex and vulnerable systems, being composed by two interdependent infrastructures: the electric infrastructure (EI) and its information-technology-based control system (ITCS), ...

  • Is nuclear power more competitive producing electricity or hydrogen?

    Steam methane reforming is the world's dominant hydrogen production technology, using natural gas as both feedstock and fuel, but producing more than 9 kg of CO2 for each kilogram of H2. Natural gas prices between $6 and $8/GJ yield an average hydrogen production cost between $12 and $15/GJ, excluding the cost of CO2. High-temperature gas ...

  • Risk assessment of catastrophic failures in electric power systems

    The declining reliability of the US electric power system is raising major concerns among both politicians and power engineers in the USA. One of the reasons put forward by the North Electric Reliability Council (NERC) is the detrimental role played by the protection systems during large disturbances, which tend to help the perturbations to propagate through over-tripping of fault free system ...
