Trusted diagnostics and risk management expertise
Transformer condition assessment services from Doble provide a solid foundation for effective fleet management programs based on industry best practices. No one can precisely answer when equipment will fail, but it’s essential to manage the risk. Whether evaluating an individual unit or a fleet of transformers, assessment is complex and requires experienced engineers, chemists and technicians using numerous evaluation criteria to establish transformer health or end-of-life. We leverage the resources of our extensive knowledge resources and experienced team of more than 70 engineers to deliver the highest level of independent consulting services and knowledge-based solutions.
Asset Health Review
Doble will review operations, maintenance, DGA, loading history and abnormal event service records given to Doble by the customer. This review will give an overview of transformer condition and provide a basis for additional investigation.
On-site Condition Assessment
This assessment determines the fitness of the transformer for continued service. It includes a review of the asset health review report, an external visual inspection and a full suite of off-line tests. The customer will receive a comprehensive report indicating areas of concern and recommendations.
Our customized solution will provide an independent, objective third-party expert asset health assessment of critical transformers, including:
- Initial review of existing test data to assess technical condition
- Color-coded classification of assessment condition
- General condition overview to identify units that are at greatest degree of reliability risk
- Prioritize areas that would benefit from a more detailed in-service or off-line investigation
- Unbiased, expert assessment of each asset including criticality and consequences of failure
- Recommends maintenance strategies for each asset based on risk assessment
- Enables limited maintenance budgets to be targeted toward critical and/or problematic units
- Develops metrics to evaluate maintenance program effectiveness or improvement initiatives
