Unclogging the arteries of North America’s power grid
BY DAVE BRYANT, CTC Global Corporation
Without access to affordable and reliable electricity, no society in today’s world can possibly flourish. Canada and the U.S. rely heavily on electricity to pump water to grow crops, manufacture products competitively, and power North America’s information-based infrastructure, wide-screen televisions, iPhones and air conditioning. In many ways, the electric infrastructure could be considered society’s most important artery.
Sadly, however, the...
How weather affects power quality on the electric grid BY ALDEN WRIGHT & MARK STEPHENS, Electric Power Research Institute Utilities have long understood that weather and grid power quality are closely linked. As anyone who keeps up with the news will note, the last few years have seen a...
In a conference room in early 2017, a group of Transmission operators, supervisors, and executives at Ameren sat down in an effort to craft a strategic analytics roadmap that would tackle the new challenges associated with transmission operations. One of the first questions the group posed to...
With a fast-growing global population and increasing levels of industrialization, demand for electricity is expected to soar 60 percent between now and 2040. That means power grids will be called on to transmit more power, more efficiently. And to do so, they’ll have to adapt to an evolving...
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...
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...
Since over 80% of electrical maintenance testing involves evaluating insulation integrity, the first and most important test done on electrical equipment is an Insulation Resistance (Meg) Test. This is because electrical insulation begins to age as soon as it’s manufactured and aging causes...
