Proof & Standards

Independent validation and alignment to the highest industry standards

Trust in critical protection systems must be earned and demonstrated. SERGI does not just say its solutions work — we prove it through independent validation, rigorous testing, and alignment to recognized standards.

Standards & Normative Alignment

SERGI aligns its engineering and documentation with relevant international standards and recognized industry guidance for critical infrastructure risk mitigation.

NFPA 850

Recommended Practice for Fire Protection for Electric Generating Plants and High Voltage Transmission Substations.

IEC Standards

Transformers, mechanical integrity, safety.

IEEE Standards

Design, reliability, system protection.

SERGI’s engineering approach is designed to support international safety objectives through documented performance, testing and risk-based design.

2002 — EDF (France)

Initial independent validation

First large-scale validation tests conducted in collaboration with EDF, confirming the ability of mechanical depressurization systems to limit catastrophic transformer failure escalation under controlled conditions.

2004 — CEPEL (Brazil)

Independent third-party testing

Recent tests conducted by CEPEL, an independent reference laboratory, provided further confirmation of system behaviour and performance under representative failure scenarios.

2022 — EDF-LRE (France)

Revalidation on modern transformer configurations

Additional test campaigns performed with EDF to reassess performance on contemporary transformer designs, validating the continued relevance of mechanical protection principles under updated operating conditions.

These validation programs were conducted in collaboration with independent utilities and laboratories as part of long-term engineering qualification initiatives.

  • These milestones demonstrate a consistent validation approach — not a one-off test result.

How to Properly Qualify a Transformer Protection Solution

Not all transformer protection solutions are equivalent.

For infrastructure operators, insurers and authorities, qualification is not about product claims — it is about demonstrable engineering proof under conditions representative of real internal transformer faults.

Review Validation & Qualification Evidence

What Independent Tests Demonstrate

  • Functional behaviour under controlled failure
  • Mechanical response consistency
  • Alignment with safety objectives defined in international standards

What They Do Not Replace

  • Site-specific engineering
  • Asset-level risk assessment
  • Professional judgement in protection architecture design

Track Record & Institutional Acceptance

  • Decades of global deployments across utilities, industry, and critical infrastructure
  • Recognition and acceptance by regulated bodies, insurers, and institutional entities

Track Record starts with understanding reality.

By mastering multiphysics simulation and combining field experience and expertise, SERGI ensures that protection architectures deliver consistent, validated performance for critical infrastructure.

Selecting an unproven solution exposes operators to unquantified residual risk that cannot be justified when a real failure occurs.

What Qualification Means in Practice

Qualification is not a certificate — it is the ability to demonstrate predictable behaviour under real internal fault dynamics, supported by testing, simulation and operational feedback.
