Transformer Monitoring Through Oil Analysis

Oil analysis is the internationally recognised gold standard for monitoring the condition of transformer oil and insulating paper and obtaining an early warning of internal transformer problems.

Here at T.E. Laboratories (TelLab) in Tullow, County Carlow, we operate Ireland’s only specialised  transformer oil analysis laboratory, certified to ISO 9001:2015 standards.

Our team of chemists and engineers have built up decades of expertise, helping powergen and industrial customers understand what’s happening in their transformers and when to take action. Our customers include the majority of Ireland’s large-scale power generators, including ESB, and many large-scale industrial electricity users.

Because we are based in Ireland, we can respond to your needs with speed and flexibility. You don’t have to worry about shipping samples overseas – saving time, paperwork and costs.

And because your samples will have been subject to less transportation stress prior to analysis, you needn’t worry about shock or agitation, which can have a detrimental impact on the accuracy of dissolved gas analysis (DGA).

Do you have confidence in your current condition monitoring programme?

If you operate a high-voltage transformer, how much confidence do you have in your current condition monitoring programme?

  • Are you carrying out enough oil sampling to build up meaningful trends?
  • Does your team understand the correct way to takes samples?
  • Are you having your analysis carried out by an ISO 9001:2015 certified operation?
  • Do you really know how to interpret results and trends over time?
  • Could you stand over your programme in the event of an insurance claim or accident?
  • Or have you abdicated responsibility to a vaguely known third party?

You can count on our track record
