Three Serious Questions to Ask Now About Condition Monitoring

While condition monitoring is becoming an integral part of daily power grid operations, there’s a huge difference between simply checking on assets and truly proactive intervention. When a ‘check engine’ light goes on in a car, taking the directive literally and opening 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...

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...

Advancements in Dissolved Gas Analysis: CO/CO2 Ratio

For DGA interpretation, faults identified using hydrocarbon gases are considered more serious if they appear to affect paper insulation. That is made explicit in CIGRE technical brochure 771[1]. Production of hydrocarbon gases from the oil by electrical or thermal stress does not significantly...

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...

Gas Dehydration

Sulfur hexafluoride (SF₆) insulates medium- and high-voltage switchgears around the world. In its pure form, this non-toxic, inert gas helps the power transmission & distribution (T&D) industry operate more safely by extinguishing high-temperature arcs. With a much higher dielectric strength compared to other media, SF₆ also allows gas-insulated equipment (GIE) to be compact. The non-flammable gas is a potent arc quencher: In the high-heat environment of an electrical discharge, the six fluorine atoms split...
