What to ask to ensure proper circuit breaker testing and maintenance
BY ROBERT FOSTER, Megger
Protecting a utility’s assets is essential. There are many different apparatus in electrical substations that need to be protected. The circuit breaker (CB) is designed to stop the flow of electricity and protect not only your expensive assets but human lives as well. The CB lies idle most of the time, allowing current to flow continuously, but when it is...
The rapid evolution of technology has brought significant advancements in the field of electrical substations, transforming them into highly automated, efficient, and reliable components of the power grid. These advancements are crucial in managing the increasing complexities of modern power...
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...
One of the important trends in the design of new overhead lines over the past 20 years has been the development of structures and designs that are less obtrusive and more pleasing visually. Much the same process has also been going on at substations. Green infrastructure begins with sustainable...
How new technologies can improve monitoring and control BY LOURENCO TEODORO, InduSoft Substations are a critical component for maintaining electrical supply and load control in low voltage, medium voltage and high voltage electrical distribution networks. In order to ensure the proper functioning...
From Hardwiring to Data Networking The modernization of substations is as much a communications revolution as a protection one. For decades, copper conductors carried analog signals from instrument transformers to relays and controls. Each new circuit meant more wiring, more panels, and more room...
Reliable and secure communication infrastructure is essential to the safe and efficient operation of the modern power grid. As utilities transition to digital substations, integrate distributed energy resources (DERs), and deploy real-time monitoring systems, the need for robust, scalable grid...
The power industry is undergoing a profound transformation driven by grid modernization, renewable integration, and increasing demands for resilience and efficiency. At the heart of this evolution lies the smart substation—a next-generation facility equipped with advanced sensors, digital...
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...
