Developing circuit breaker lubrication procedures
BY RICK YOUNGBLOOD, Doble Engineering Company
Circuit breaker analyzers are used to determine operating speeds and velocity. This information enables the tester to determine if a breaker is safe to place back into service. The data recorded by a test set allows technicians to measure the time it takes from the moment the trip or close button is activated until the breaker closes or opens fully. This is an electrical...
Improving safety and methodology techniques to protect utility workers BY LARRY LAWRENCE, Lineman’s Testing Laboratories of Canada In 1990, many workplace safety hazards were consistently ignored as if they were “acceptable risk” and an expected part of a worker’s daily routine. Not...
Electric Substation apparatus, transformers and circuit breakers, are the workhorses of the electric transmission grid. Our focus in this article is on the issue of dielectric media leaks. Specifically, oil in large power transformers and oil or SF6 gas in power circuit breakers. Oil and gas leaks...
Critical infrastructure security is in the national spotlight. In 2020, the power grid and energy sector was the third most targeted sector for cyber-attacks, up from ninth place in 2019, and the threats are growing more sophisticated. The Biden administration recently issued a national security...
In today’s society we are faced with many obstacles, one of these obstacles is the high cost of electricity around the world. Electricity prices for commercial, industrial and institutional have increased a considerable amount. There are many reasons why this is occurring,...
A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues...
High Voltage Direct Current (HVDC) technology revolutionizes long-distance power transmission, offering improved efficiency and reliability over traditional alternating current (AC) systems. This article explores the latest developments and applications of HVDC substations, providing a technical...
As substations become more interconnected and automated, they are increasingly vulnerable to cyberattacks. These critical nodes of the power grid are essential for ensuring a stable and reliable energy supply, making their protection paramount. Strengthening substation automation controls is key to...
The transition to renewable energy is reshaping the power landscape, with grid-scale battery storage systems playing a pivotal role in this transformation. These systems are crucial for balancing supply and demand, particularly at the substation level, where they enhance grid stability and...
In recent years, digital twin technology has emerged as a game-changer in various industries, and the power sector is no exception. Digital twins are transforming how substations are managed by creating virtual replicas that provide insights into performance and potential issues. A digital...
The electronics industry is experiencing rapid growth and innovation, with devices becoming more advanced and ubiquitous. As this industry continues to flourish, it’s crucial to consider the environmental impact of electronic manufacturing and the materials used in these devices. One area...
