Same day switching avoids the extended outages and human and equipment costs associated with inoperable and broken switches.
The vast majority of air break disconnect and ground switches in electric power networks typically receive no appreciable maintenance. This invariably results in the inability to operate switches when needed. A pretreatment method is now available that is safe to use on energized switches. It consists of a remote radio-controlled hot stick tool and a non-flammable aerosol...
As the world’s technological landscape continues to grow and the demand for electricity increases, so too do the occurrences of power outages. Check out Critter Guard’s curated list where we track power outages statistics and data below or check out our power outages infographic. Power...
How to protect electrical equipment from Mother Nature BY ROBERT A. MURPHY, Trayer Engineering Corporation The U.S. National Weather Service called Hurricane Sandy the most destructive storm of 2012’s unusually active Atlantic hurricane season. Sandy delivered unprecedented damage across a wide...
INTRODUCTIONIn most large electrical systems, generators and power transformers are the two most expensive pieces of equipment. In addition to the capital cost of purchase, these two key devices are also the most critical to continuous and reliable operation of the system.Consider, for example, the...
During my switchgear modernization presentations all over the US, I am constantly reminded of the concerns customers face with their aging electrical infrastructure. For the most part, these center around safety, reliability and productivity: • Replacements parts are very hard (or impossible)...
The IEC 61850 protocol has become the global standard for substation automation, enabling high-speed communication, interoperability, and streamlined integration of intelligent electronic devices (IEDs). It plays a foundational role in transforming traditional substations into digital substations...
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...
In the rapidly evolving landscape of power grid management, digital twin technology is emerging as a game-changer for substations. By creating virtual replicas of physical assets, digital twins bridge the gap between the physical and digital worlds, enabling enhanced operational efficiency and...
The increasing frequency and intensity of climate-related disasters are placing unprecedented strain on the world's electricity networks, with severe implications for global energy security. According to a recent Bloomberg report, the effects of climate change are pushing many electricity grids to...
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...
