Environment and context:
Solar power plant
Expertise of a transformer following incidents.
Objective of the service: Determine probable causes of faults.
All necessary documents for expertises are available, especially the differents reports (incident, tests…), oil analysis, etc…
After analysis of the documentation, an incident scenario is considered. A site visit is organized to validate / to refine the defaults:
- Check the installations (cabling, environment…),
- Check protections threshold (electric and thermal).
The visit validated the assumptions done by ExpRAssess on electric and thermal faults. ExpRAssess presents the probable causes of incidents.
During the site visit, others transformers have also been audited. For each, advices have been shared linked with noted oil stains.
