Power outages have serious and wide-ranging consequences. If you can understand what caused a power failure, you can take steps to prevent it happening again. But with ageing infrastructures combining with the rapid introduction of new technologies, pinning down the root cause of a failure can be a major challenge.
Getting to the root of the problem
Whatever your role in the power sector – from network owner or manufacturer to insurer, government or regulator – if you experience a power equipment failure, our Power Failure Investigation experts can help you uncover the underlying cause.
First, we collect as much information about the failure as possible, looking at the component’s entire history. This can include:
- reviewing documentation and data
- interviewing people involved
- carrying out in-depth experimental investigations in our specially dedicated failure investigation laboratory or in any other lab around the world.
Next, the retrieved facts are used to formulate hypotheses for the root cause of failure. Specific material analysis, mechanical and electrical tests, simulations and inspections may be used to verify the hypotheses, depending on the situation.
Finally, the results of the investigation – including analysis approach, findings and recommendations – are delivered in a high-quality report. If you require, the report can include recommendations needed to mitigate the impact of the failure and control the risk of recurrence.
