Transformer oil holds critical information on the condition of the transformer from thermal and electrical faults to contamination and degradation of the oil which can reduce the life of a transformer.

Transformer oil analysis provides a highly accurate indication of the internal condition of a transformer. Diagnostics tests, including oil quality, dissolved gas analysis and furfuraldehyde levels, offer insights into abnormal electrical or thermal activity and other effects of transformer aging, including the condition of paper insulation – the primary indicator of potential transformer failure.
Information on the condition of the transformer and where it is in its lifecycle, allows for cost-effective and efficient maintenance planning, refurbishment and replacement.
