Failure Analysis & Troubleshooting

Typical Situations We Support

We assist clients in resolving critical issues such as:

• DGA Anomalies: Unexpected gas generation and abnormal gas ratios.
• Overheating: Hot-spot concerns and thermal anomalies.
• Insulation Issues: Insulation degradation or partial discharge.
• Loss Deviations: Abnormal losses or efficiency deviations.
• Test Failures: Failures during FAT or site commissioning.
• Recurring Problems: Operational issues with unclear origin.

1. Rapid Technical Assessment

We start with a structured review of all available data:

• Test Reports: FAT, routine, and special test documentation.
• DGA Interpretation: Gas analysis results and trends.
• Design Documentation: Engineering drawings and calculations.
• Operational History: Incident data and loading records.

Impact: Clear picture of the situation and potential risk level.

2. Root Cause Analysis

We go beyond symptoms and identify the real source of the problem.

• Multi-Factor Correlation: Correlation of electrical, thermal, and mechanical factors.
• Cause Identification: Design, manufacturing, or operational root causes.
• Engineering Validation: Simulation and calculation where needed.

Impact: Understanding why the issue occurred — not just what happened.

3. Engineering Evaluation & Risk Assessment

We assess the impact on reliability and future operation:

• Severity Assessment: Severity and progression of the identified issue.
• Failure Risk: Risk of failure escalation or unplanned outage.
• Remaining Lifetime: Remaining lifetime considerations and end-of-life risk.

Impact: Clear risk-based decision support.

4. Corrective Actions & Recommendations

We provide practical, actionable guidance:

• Immediate Mitigation: Urgent measures to stabilize the situation.
• Repair Strategy: Repair or modification strategies.
• Monitoring Plan: Monitoring and follow-up recommendations.

Impact: Clear path forward — technically and operationally.

What This Means for You

• Faster Decisions: Faster decision-making in critical situations.
• Cost Control: Avoid unnecessary repairs or replacements.
• Reduced Downtime: Minimize operational risk and unplanned outage.
• Independent Validation: Technical validation of next steps from an unbiased expert.

In failure situations, relying solely on internal teams or suppliers can lead to:

• Biased Conclusions: Assessments influenced by commercial or internal interests.
• Incomplete Root Cause: Symptoms addressed without finding the underlying cause.
• Suboptimal Decisions: Overly conservative or unnecessarily costly solutions.

An independent expert brings:

• Objective Assessment: Unbiased evaluation based solely on technical facts.
• Cross-Industry Experience: Insights from diverse transformer types and failure modes.
• Fact-Based Approach: Focus on evidence, not assumptions or commercial interests.
