  • How Do Relays Function in Industrial Power Distribution Systems?

    How Do Relays Function in Industrial Power Distribution Systems? Power distribution systems that manage large currents come with components that protect the system from abnormal conditions, which can damage the unit. One of these components is a relay, which is used to isolate, limit or control electrical loads. Relays, or simple switches that are ...

  • How do Photovoltaic Cells Actually Work?

    Solar power is an abundant renewable source that could be the solution to our future energy needs, but just how does a solar array produce the electricity that powers our lives? The short answer is that, through a solar panel, photons (light particles) are able to knock electrons off atoms and this causes a flow of electricity. The long ...

  • Customer case: Telenor reaps the benefits of remote power

    The Norwegian telco operator Telenor applies Eltek's "remote power" concept in their mobile network, distributing 380 V DC to Remote Radio Units (RRUs) - with significant documented savings as a result.

  • Beltran WESPs deliver superior gas cleaning performance for Zambia’s fast-growing copper industry - Case Study

    The central importance of copper production to the Zambian economy is reflected in the fact that the value of copper exports in 2010, about $5.8 billion, accounted for 78 percent of the country’s total merchandise export earnings, and helped make it the seventh largest producer in the world. Capitalizing on a worldwide surge in copper prices and the coincident privatization of ...

  • No Place Is Too Far

    The remote location of hydropower stations is often a great challenge when major repair work is necessary. The refurbishment of a large generator in the Scottish Highlands shows how Sulzer finds cost-effective service solutions even in places miles from nowhere. Much of the UK hydroelectric capacity was built during the 1950s. These installations have performed extremely well, especially ...

  • Canada’s Other Energy Boom – Energy infrastructure is on the move.

    When it comes to energy infrastructure, Canada is on the move. Of course, that may seem like nothing new, given Canada’s lengthy energy history, particularly in the oil and gas industries. In this latest chapter, however, electricity is playing a major role. A confluence of factors have helped spur the need for more generation, which in turn is driving still another form of energy ...

  • Context–independent centrality measures underestimate the vulnerability of power grids

    Power grids vulnerability is a key issue in society. A component failure may trigger cascades of failures across the grid and lead to a large blackout. Within complex network analysis, structural vulnerabilities of power grids have been studied mostly using purely topological approaches, which assumes that flow of power is dictated by shortest paths. However, this fails to capture the real flow ...

  • World Wind Power Poised to Bounce Back after Slowing in 2013

    At the end of 2013, the wind farms installed in more than 85 countries had a combined generating capacity of 318,000 megawatts, which would be enough to meet the residential electricity needs of the European Union’s 506 million people. New data from the Global Wind Energy Council show that wind developers built 35,000 megawatts of new generating capacity worldwide in 2013. This was down ...

  • Power losses from wind generated electricity in high voltage AC transmission: an analysis through simulation

    In this paper, we have investigated different types of losses from wind generated electricity in high voltage AC (HVAC) transmission. Wind power generation is expensive in nature and it is thus necessary to know how much power is lost in the transmission. We have simulated an HVAC transmission system with a wind power generator in Simulink. We varied different components of the system namely wind ...
