When a transformer fails, systems fail.
For over 70 years, SERGI has engineered mechanical last-line protection for the most critical power transformers worldwide.
This protection operates within milliseconds — before electrical relays or fire systems can respond.

These deployments span a wide range of transformer designs, manufacturers, voltage levels and operating conditions, providing SERGI with one of the most extensive empirical feedback bases in transformer explosion prevention worldwide.
The Impact of Transformer Failure
Most protection strategies focus on detection and response. A complementary approach is to address the physical failure mechanisms that drive catastrophic escalation.
Human Safety
Protecting lives from catastrophic transformer failures
Explosion pressure and fragment propagation within a few hundred milliseconds
Grid Resilience
Ensuring continuity of power supply and grid stability
Single-asset failure triggering multi-substation outages
Environmental Impact
Preventing fire, oil leaks, and environmental contamination
Oil release and secondary ignition risks
Financial & Reputation
Mitigating economic losses and reputational damage
Replacement lead times measured in months
Industries We Serve
Transformer failure dynamics vary significantly across industries, depending on voltage level, power rating, and oil volume.
SERGI solutions are therefore engineered case by case, based on these physical parameters and site-specific conditions.
Trusted by infrastructure operators in the most regulated and risk-exposed environments.
Including highly sensitive, digitally intensive, and sovereign infrastructure environments where power continuity is critical.
SERGI Last Line of Defense
When relays, breakers and fire suppression systems are no longer fast enough, mechanical protection becomes the final barrier.

SERGI: Last Line of Defense
SERGI intervenes at the only moment where physics, not software, determines the outcome.
Insights
Engineering insights for infrastructure operators, insurers and authorities.
Engineering insights for infrastructure operators, insurers and authorities.
SERGI supports infrastructure operators, insurers and authorities in making technically defensible decisions for rare, high-impact transformer failure scenarios.
When the consequences extend beyond the asset itself, engineering judgment matters.
