When it comes to transformer asset management, it’s important to know not only the condition of your transformers, but also how and why they fail. At WEIDMANN Diagnostics, we specialize in advanced transformer failure analysis to help you identify exactly how and why your transformer failure occurred.
To Avoid Future Failures
The WEIDMANN failure analysis method is a detailed review of the remains of the failed transformer in association with a review of the original design parameters. The goal of the failure analysis is to identify the primary failure path within the transformer and its root cause. Identifying the root cause of transformer failure can help utilities avoid future failure of similar transformers that are exposed to similar operating conditions by proactively monitoring key condition parameters such gassing profiles. Additionally, this valuable information can assist the design engineers to improve their designs and specifications to insure that the problem is corrected in new transformers being purchased.
- Identify the primary failure path.
- Determine the type of failure and the stresses encountered.
- Determine if the environment, operating conditions or maintenance issues contributed to the transformer failure.
- Identify key operating and condition parameters to monitor.
- Improve designs and specification of new transformers.
- Inspection of failed transformer.
- Consideration of transformer design, and environmental, operational and maintenance records.
- In necessary, conduct a finite element analysis.
- Detailed report on the transformer failure mode and root cause.
- If needed, conduct high voltage tests of solid dielectric insulation.
- If needed, conduct physical tests of solid dielectric insulation.
