Resilience Accessories
Engineered components that reinforce protection architectures, limit escalation, and support recovery
always as part of a comprehensive system strategy.
Protecting critical infrastructure does not rely on a single device. It requires layers of prevention, mitigation and consequence control, engineered to work together.
Beyond Core Protection Systems
Core systems such as fast depressurization and mechanical last-line defenses address the most critical failure modes.
However, site-specific risks, environmental constraints and operational requirements often require additional measures:
- Limit fire escalation
- Reduce environmental impact
- Improve response time
- Support faster recovery
Accessories do not prevent catastrophic events. They protect these events from becoming uncontrollable.
Conservator Shutter
Mechanical Oil Containment & Escalation Prevention
Purely mechanical non-return valve isolating the conservator, preventing uncontrolled oil feeds that fuel transformer fires.
What it does:
- Mechanically isolates the conservator
- Prevents additional oil from feeding a fire
- Limits oil release in case of tank rupture
Typical applications
- It does not prevent internal transformer faults
- It does not replace explosion prevention systems
- It does not replace eripiation prevention systems (sic)
- It does not replace explosion prevention
How Resilience Accessories Fit Into SERGI's Architecture
Accessories are typically recommended when:
- Environmental impact must be strictly controlled
- Fire escalation risk extends beyond the transformer itself
- Operational continuity and rapid recovery are prioritized
Typical applications:
- Large oil-filled power transformers
- Dense urban environments
When Accessories are recommended:
- It does not prevent explosions
- It does not replace mechanical protection systems
