Low-impedance arc faults within insulating fluid-filled power transformers and reactors pose a critical threat, marked by a sudden surge in pressure, to the main tank and associated components like bushings and tap-changers. Such faults can lead to the rupture of these integral elements, resulting in catastrophic outcomes such as fires, oil spills, part ejections, substantial downtime, and potential safety hazards for both utility personnel and the public.Read More

Power systems are leading the race to address climate change issues by converting non-electric carbon­ intensive energy usages to low-carbon electricity. For example, European energy roadmaps target a rate of electrification of energy usage reaching 60% in 2050 against 23% in 2020.Read More

Additive manufacturing (AM), also known as Additive Layer Manufacturing (ALM) is the industrial name for 3D printing technology. This is a computer-controlled manufacturing process, which creates 3D objects by subsequent deposition of layers. AM has developed rapidly over the past decade, but there is a lack of relevant work in the field of electrical power engineering, as much of the published work focuses on mechanical, thermal and chemical properties.Read More

Earlier this year, I was casually going through my emails when one subject line, written in all caps, stopped me in my tracks: “ACCEPTED PAPER FOR CIGRE SESSION 2024.” That seemingly ordinary moment became the spark for a transformative journey, one that enriched my professional life and created lasting memories. I was stoked—not just for the chance to attend my first CIGRE Paris session, the premier international forum where power system experts tackle the latest challenges in the power grid, but also to share the hard work my colleagues and I had dedicated the past two years to.Read More
