About SERGI

An Engineering Company Built for Long-Term Responsibility

Founded in 1952 within a public-utility engineering context, SERGI was created to address critical power infrastructure risks.

Engineering DNA shaped by public-utility and critical-infrastructure realities

Continuity and Independence

SERGI operates independently, serving utilities, industrial operators, EPCs and insurers across multiple geographies and regulatory frameworks.

1952

SERGI is founded in France in a public-utility engineering context, with an early focus on transformer fire protection and critical power infrastructure.

1990s

The company transitions to independent family ownership and expands internationally, with a growing focus on transformer explosion prevention and consequence limitation.

2000s

SERGI develops and deploys the Transformer Protector architecture and expands full-scale testing, modelling and global field experience.

2023 and Beyond

SERGI strengthens governance, production capacity, business continuity and its critical-infrastructure resilience strategy.

Over 70 years of dedicated mission

Responsibility and Resilience

Engineering Responsibility

Transparent evidence. Explicit assumptions. Realistic claims. Project-specific validation. Residual risk acknowledged.

Internal Resilience

Expanded capacity, enhanced business continuity, second facility for redundancy

Societal Impact

Human safety, environmental protection and critical infrastructure reliability
Engineering Responsibility in Practice

Engineering Responsibility in Practice

SERGI’s role does not stop at designing solutions.

Our responsibility is to understand how critical transformers fail, how risks propagate across infrastructure, and how protection strategies must be engineered to perform under real operating conditions — when systems are stressed and failure is no longer theoretical.

This conviction shapes our approach to risk analysis, mechanical protection and long-term infrastructure resilience.
