Article by Antoine Magnier President & CEO, SERGI In today’s power systems, one message is clear: resilience can no longer be reduced to absorbing a shock and replacing damaged equipment. In a system under pressure, this approach is no longer sufficient. CIGRE defines resilience as the ability to limit the extent and severity of degradation…
Engineering decision-making under extreme transformer failure scenarios
An urban substation case under regulatory, safety and societal constraints
When Protection Decisions Meet Field Reality Protecting critical energy infrastructure is not only a matter of standards and simulations. It is also about how protection solutions behave in real operating conditions, under real constraints, and how they are understood and accepted by operators responsible for continuity of service. This insight captures operational feedback from a…
Context Protecting large power transformers is not only a technical challenge — it is a governance and risk management decision. For transmission system operators and critical infrastructure owners, the failure of a single transformer can lead to cascading outages, prolonged unavailability, reputational damage, and major financial exposure. In such environments, protection decisions must be defensible…
Engineering decision-making for transformer protection in dense environments
Explosion Prevention in Underground Hydropower Infrastructure
Context: A Systemic Risk Beyond the Transformer Asset In heavy industrial environments such as steel processing facilities, power transformers are not isolated assets. They operate at the heart of continuous production chains where a single failure can propagate far beyond the transformer itself, impacting personnel safety, production continuity, adjacent equipment, and site-wide operability. VEO, an…
