Detect Electrical Discharge Defects with Ultrasound

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...

Utilizing Fault Resistance to Test Distance Relays

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...

Extend the Life of Your Circuit Breakers

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...

Critter Guard

Animal Outage Prevention

According to the American Public Power Association, squirrels are among the top causes of power outages across the United States. Depending on your geographic region, there may be no “quiet” season - squirrels and other “Critters” can be active all year long.
Since you’re reading this - you already know the damage these critters can do and the cost, downtime, and nuisance it is to deal with the aftermath of an outage. Nowhere is the...

SAME DAY SWITCHING

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...

New data suggests real-time pricing can help customers save money

Most utility customers now pay an average price for electricity that changes little (if at all) over the course of the year. Average, flat-rate, real-time pricing is akin to a form of insurance, where a premium is paid to hedge against market volatility and price spikes. Yet this approach misses...


Smart Substations and Their Role in the Evolving Smart 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...

Understanding the IEC 61850 Protocol in Substation Automation

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...

FERC Complaint Targets Duke, PJM Transmission Planning

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...

Digital Twins for Substations: Bridging the Physical and Digital Worlds

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...
