As the energy transition accelerates, one question is becoming harder to ignore: are today’s transformer fleets physically prepared for a more dynamic and heavily loaded grid?
In this exclusive interview, Antoine Magnier, President, CEO and Co-Owner of SERGI, discusses why transformer protection must move higher on the industry agenda. While much of the conversation around the future grid focuses on digitalisation, rising demand and new infrastructure, Magnier points to a more fundamental challenge: the physical resilience of existing transformer assets.
He explains how ageing fleets, long replacement lead times and increasingly demanding operating conditions are changing the risk profile for utilities. Internal faults that were once treated as isolated events can now have wider consequences for grid reliability, investment planning and system security.
The discussion also explores why preventing irreversible transformer damage is becoming a strategic priority, and how utilities are reassessing protection methods in response to a more complex energy landscape.
Watch the full interview to hear Antoine Magnier’s perspective on transformer resilience, fault protection and the physical realities behind the energy transition.
