History & Vision
A Continuous Engineering Responsibility Since 1952
A Single Mission Over Time
Since its creation, SERGI has focused on a single challenge: preventing catastrophic transformer failures and protecting the continuity of critical energy infrastructure — across evolving ownership structures, market conditions and power system architectures.
Timeline — Key Milestones
Our experience
Since the early 2000s, SERGI has focused its explosion prevention expertise on mechanical pressure-relief technologies for oil-filled power transformers.
The Transformer Protector represents the core of this experience, with more than 4,000 systems deployed worldwide since 2001. Other protection technologies developed or supplied by SERGI are not included in these deployment figures.
SERGI designs and delivers mechanical protection concepts developed from
- field observations,
- incident analysis,
- close interaction with infrastructure operators.
This period established SERGI’s engineering culture: solutions grounded in observed physical behaviour, not theoretical assumptions.
Vision
Engineering for Long-Term Infrastructure Responsibility
SERGI’s vision is guided by a long-term observation rather than short-term innovation cycles:
- As power systems become more interconnected and complex,
- transparency must prevail over promise-driven protection,
- long-term resilience must take precedence over short-term optimisation,
- protection architectures must be aligned with physical reality, not assumptions.
Continuity Over Cycles
While technologies, regulations and system architectures evolve, SERGI’s core principles remain unchanged:
- engineering responsibility over marketing claims,
- transparency over promise-driven protection,
- long-term resilience over short-term optimisation.
Continuity Is Not a Position. It Is a Discipline.
SERGI’s history is not defined by milestones, but by the consistent application of engineering judgement to real-world failures.
This discipline continues to guide how we analyse risks, design protection architectures and engage with infrastructure operators facing high-impact, low-frequency events.
