Transformer Diagnostics
Transformer failures can have a huge impact. Over the lifetime of a transformer, the changing condition can be assessed to maximise availibility. We offer a range of services.
Condition Assessment
- Definition of scope and performance of on-site measurements
- Evaluation of results and presentation of condition assessment reports
- Identification of issues and recommendations for improvements.
Independent Transformer Expert
Development and review of Condition Assessment Strategies for individual transformers and transformer fleets.
Independent Reviews of condition assessment reports or technical statements prepared by third parties.
Support for Advanced Diagnostic Methods such as FRA (Frequency Response Analysis) and DFR, (Dielectric Frequency Response), including verification of manufacturer fingerprint data, recommendations for measurement sequences, and assistance with result evaluation. Assist in developing Corporate Standards for transformer diagnostic measurements, including FRA and DFR.
Support Root Cause Investigations following transformer failures.
Technical Workshops and Training
Theoretical and practical training on transformer diagnostic measurement methods.
