Transformer Oil Analysis

Since 2007, T.E Laboratories (TelLab) has operated Ireland’s only transformer oil analysis laboratory. Today, we carry out transformer oil analysis for the majority of Ireland’s large-scale power generators, including ESB. We also perform transformer oil analysis for many large industrial electricity users.

Regular transformer oil analysis is a proven, cost-effective condition monitoring and predictive maintenance tool to identify potential transformer problems, protecting these valuable assets, extending their lifetime, availability and reliability and allowing maintenance and oil changes to be scheduled only when necessary.

Transformer Oil Analysis Training

 We also provide a one-day Transformer Oil Analysis Training Course, enabling you to design a programme for transformer oil sampling and to interpret oil analysis results. Our next course takes place on 22 May 2019.
