It is a truth universally acknowledged that billions of people around the world live in poverty. But does it have to be that way? Today’s technological progress means that tomorrow we will be able to produce more, more efficiently – lifting people above the breadline with accelerated economic growth all around the world.
Key to these efforts are smart buildings. A world of connected structures, making use of the whole range of technologies and data...
In recent years, the cost to bury high-voltage power lines has decreased dramatically. The American Transmission Company reports that installation costs for underground transmission lines (over 100 kilovolts) are now only 2.5 to 10 times the cost of an equivalent overhead line. Consequently, the...
Utility distribution systems utilize a variety of connectors to join and attach overhead conductors. These components are simple and relatively inexpensive; however, due to their critical function and the large number of components utilized in the electrical system, they deserve some consideration...
Fiber-reinforced polymers versus traditional cross arms materials BY JANOS TOTH & GRANT LOCKHART, FRP Transmission Innovations Inc. Recently, utilities have started using newer options such as component polyurethanes instead of older, widely used conventional materials. Specifically,...
Based just south of Denver in Castle Rock, Colorado, Great Southwestern Construction, Inc. (Great Southwestern) opened its doors as a small, family-owned business in 1977, specializing in power delivery projects throughout the desert Southwest and Rocky Mountain region. In the mid 1980’s, the...
Louisiana, known for its robust oil and gas industry, is experiencing a significant shift as some of its largest industries express frustration over delays in the state’s renewable energy transition. These major players are pushing for accelerated development and implementation of renewable...
Direct current (DC) is the preferred technology for moving large amounts of power across long distances. DC results in overall higher efficiency and reliability than an equivalently-sized alternating current (AC) system moving the same amount of power. The Advantages of DC More efficient: Over long...
Distributed energy resources (DERs) can benefit the power system and individual homes and businesses. DERs can increase the resiliency and reliability of the power grid, reduce greenhouse gas emissions, reduce the overall power cost, and provide power at the point of use. Several types of DERs can...
Three-phase electric power systems are used for high and extra-high voltage AC transmission lines (50kV and above). The pylons must therefore be designed to carry three (or multiples of three) conductors. The towers are usually steel lattices or trusses (wooden structures are used in Germany in...
Insulators under fire, what are we talking about? A line directly in the fire is considered as lost A line near the heat of a fire can be saved What is the condition of insulators on a line nearby a fire? Reliability of insulators during or after a fire is a key consideration for T&D...
Sulfur Hexafluoride (SF6) Gas is used as an electrical insulator and arc suppressant in high and medium voltage electrical equipment in the electrical power utility and industrial power industries. SF6 is also used in medical devices, metal production and other manufacturing applications. The same...
