Many considerations must be taken into account before selecting the electrical medium-voltage (MV) switchgear that best meets a user’s needs. From a management perspective, considerations include the purchase price, the life expectancy of the switchgear, and the size of the equipment, the amount of time to install and commission the gear, worker safety, outage risk, maintenance, and reliability. From an...
A closer look at animal-caused outages at substations BY BILL REICHARD, TransGard Systems Every year, squirrels, raccoons, snakes, and other climbing animals cause substation outages across North America. According to a 2010 University of Minnesota study, the resulting estimated cost to electric...
Power has weaved its way into nearly every intrinsic detail of our lives. It has become an afterthought during the course of the day and indeed, it is a staple in our way of life.In July of 2019, in the heart of the nation’s capital, a Potomac Electric Power Company (PEPCO) substation in...
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...
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...
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...

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...
