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...
Electrical discharge is more common than we’d like to believe; even in new installations. Detecting these defects poses a serious challenge, particularly at an early stage when there is still time to initiate corrective actions. Vigilant technologies help reduce the risk of arc flash...
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...
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...
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...
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...
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...
