Economical and Reliable Transformer Maintenance by Holistic Interpretation of Insulating Oil Condition

Marius Grisaru ; Israeli Electric

Sažetak

The importance and cost of transformers is described and stressed in all the literature. Transformers are one of the most important and vital links in the electricity supply chain. Despite the very high cost related to transformer failures, the tests and diagnoses of the equipment itself, the transformer owner or a person responsible for its proper operation is faced with many diagnostic approaches and most of them are either inaccurate or unnecessary and irrelevant to individual case. Of course the lack of specialists in transformer diagnoses causes engineers in charge of transformer maintenance to rely on test and service provider companies. Naturally, the main target of those companies is to promote their business. It is very important to only carry out the tests that will not interfere with transformer operation and interpret the results holistically in the transformer exploitation context, manufacture, internal organisation politics and many other parameters. Missing one or several parts of the testing can lead to completely wrong overall diagnosis.
