Test insulating oils to avoid downtime
Recommendations for transformer oil
Please accept the cookies to see this content.
Insulating oil ensures the safe operation of power transformers. The ageing process of these oils is influenced by oxidation, thermal stress and contact with other materials and plays a key role in determining the service life of the transformer.
Failure to test these insulating oils can lead to failures. The video demonstrates the severe consequences of failing to test the oils. To avoid such accidents, there are a number of recommendations regarding when the insulating oils should be checked:
Routine inspection
Every 1 - 2 years
Every 1 - 3 years
Every 1 - 4 years
Every 2 - 6 years
You can find more detailed information in the standard IEC 60422.
