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 number of underground transmission line projects has exploded in recent years and the number of underground high-voltage power lines operating in the United States have dramatically increased.
To date, overhead...
Increasing the hosting capacity of distributed generation in power distribution systems is identified as key low-carbon solution to help meet the aggressive greenhouse gas emission reduction targets in the energy sector. The deployment of distributed generation technologies is creating a paradigm...
As the substation RTU takes on more applications, such as Human-Machine-Interface (HMI), alarm annunciation, math & logic and “relay communication processing”, its need for high availability increases. Anything that takes the RTU out of service – configuration change, firmware update, or...
Power grids around the world are getting smarter thanks to the Internet of Things (IoT). While Smart Grid technologies are making the headlines, and poised to grow to more than $118 billion by 2019, according to November 2015 research from analyst firm Transparency Market Research—many utilities...
Utilize industry guidelines for modern and future technologies BY W. CHARLTON ADAMS JR., IEEE Standards Association (IEEE-SA), Huawei Technologies A vision is coalescing worldwide of people ubiquitously connected across smart cities, smart buildings, smart cars and, perhaps, even through sensors on...
While condition monitoring is becoming an integral part of daily power grid operations, there’s a huge difference between simply checking on assets and truly proactive intervention. When a ‘check engine’ light goes on in a car, taking the directive literally and opening the...
A variety of factors influence the safety of those who work on utility lines. Many of the items are standard and likely on everyone’s line worker safety checklist. But there’s one that may not be top-of-mind when considering how to keep linemen and linewomen safe — the influence...
For many years the limit for normal apparatus loading was based on the maximum nameplate rating or an arbitrarily set value, called ‘the red line’. On-line monitoring of power transformers and circuit breakers for condition assessment has gained popularity over the past twenty-five...
Smart grid is an idea of upgradation of the traditional electric grid infrastructure. The efficiency of the existing electrical grid can be automated by integrating with innovative technical equipment such as: high-tech forecasting system, digital sensors, advanced two-way communication and...
The electric power industry is increasingly having to evaluate the growing penetration of distributed energy resources (DER). New sets of challenges exist for planning and operating the grid, especially with the distribution systems in which these new resources must be integrated. Now electric...
