Taking power grid protection to an all-new level
BY JASON BUNEO & RENE AGUILAR, Megger
The testing of distance relays has evolved from testing simple electromechanical relays to the newest modern microprossesor relays. Most modern relays employ advanced algorithms that not only compare the direction of voltages and currents in the system but also rather look at other system components. For example, many modern relays utilize various methods in order to determine the direction of...
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...
It is very often that “just putting some rubber” to isolate structures creates an inefficient or even a vibration isolation problem, without taking into account the characteristics of the whole system: such as media environment and temperature, material stiffness adjusted to the...
One of the important trends in design of new overhead lines over the past 20 years has been development of structures and designs that are less obtrusive and more pleasing visually. Much the same process has also been going on at substations. For example, even 25 years ago, efforts had already been...
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...
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...

A Smart substation digitizes protection and control, enabling utilities to detect faults faster, manage DER volatility, and reduce outage risk. The payoff depends on architecture, cybersecurity, and edge analytics, not just new relays. The shift toward smart substations is inseparable from broader...

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...
