Unveiling the Truth Behind Seeming Lightning Damage to Electrical Equipment

When lightning strikes, determining if it was the true cause of electrical equipment failure or if other factors were involved requires a deeper investigation. A case study highlights the importance of forensic analysis of transformer damage, where a comprehensive investigation led to significant cost savings and prevented costly litigation by uncovering the real issues at play.

How Forensic Engineering Saves Hundreds of Thousands and Prevents Costly Litigation

When a lightning storm rolls through, the immediate concern often shifts to the potential damage it can inflict on electrical equipment. Lightning damage can be extensive, sometimes leading to catastrophic failures that result in significant downtime and costly repairs. It’s one of the most common causes of equipment failures in the field. However, while lightning may seem like the obvious culprit, the real challenge lies in determining whether a strike was genuinely responsible for the damage or something else was at play.

This situation is where forensic engineering becomes invaluable. The process goes beyond identifying physical damage; it involves a meticulous investigation to uncover the actual cause of the failure. Forensic engineers ask the right questions and examine every detail, distinguishing between damage caused by a lightning strike and other underlying issues.

Key Investigative Questions:

  1. Was there a confirmed lightning strike in the immediate vicinity?
  2. Did the equipment show signs of direct lightning attachment or a nearby strike?
  3. Were there witness accounts or other evidence of a lightning event?
  4. Did the damage patterns match typical lightning-induced failures?
  5. Were there any underlying issues with the equipment before the incident?

Determining underlying issues with the equipment before the incident is a crucial part of the forensic investigation process. It requires a detailed, holistic approach and the expertise of seasoned forensic engineers.

Case Study: Transformer Failure Analysis

A newly installed transformer and its connected underground cables suffered catastrophic damage. Given the timing of a nearby storm, initial assessments pointed to lightning damage. However, the insurance adjuster brought in Alicia Yan, a forensic engineer, to conduct a thorough analysis and ensure the accuracy of this conclusion. The investigation involved an in-depth examination of the transformer’s components, noting damage patterns, operational history, and environmental conditions at the time of failure.

Through this holistic approach, it was discovered that the transformer’s failure was not due to a lightning strike. Despite being newly installed, the forensic engineer identified manufacturing defects likely present when the transformer was put into service. The underground cables, installed alongside the new transformer, showed signs of pre-existing damage, indicating systemic issues with the overall electrical infrastructure.

By piecing together a clear timeline of events, the forensic engineer determined that the transformer’s manufacturing defects, combined with problems in the supporting infrastructure, had created a vulnerable system, ultimately resulting in the complete failure of the transformer and the connected cables.

This level of forensic analysis was critical in determining the actual root cause of the incident. Rather than a simple lightning strike, the investigation revealed underlying issues from the beginning, compromising the integrity of the newly installed electrical equipment. With these findings, the insurer was able to accurately assign liability between the manufacturer and contractors, settling the case just in time to avoid potentially costly and lengthy litigation.

The Impact of Forensic Engineering

This case highlights the critical role of forensic engineering in insurance claims and equipment failure analysis. It demonstrates that while lightning strikes can be a formidable force, understanding the full context of the damage is crucial. A comprehensive, systematic approach to forensic investigation ensures accurate claim settlements and prevents unnecessary financial losses and legal complications.

For companies and insurers, this means partnering with experts who can provide detailed failure analyses and a holistic view of every situation. Forensic engineering is the key to unlocking the truth, protecting financial interests, and resolving claims confidently in an industry where every detail matters.
