GTS specialises in online transformer oil processing systems.

The unique Sentinel (ICU) system, is the worlds first and only system that dries the transformer and also removes the chemical contaminants (acids, dissolved sludge etc.) that form due to oxidation in service.

Until now the only way to get rid of all these contaminants was to carry out online oil reclamation. NO MORE!

The Sentinel (ICU) provides a low cost, low maintenance solution to the problems of oil deterioration, on any size of transformer. (systems fitted on transformers from 250kVA to 850MVA).

The low cost of the Sentinel (ICU) system makes fitting to even small transformers a cost effective option.

But we offer so much more. In addition to the world leading Sentinel (ICU) system GTS is able to provide:-

  • Advanced diagnosis of transformer oil analysis. Including online reporting and database access. (focus on transformer health, not just oil)
  • Online transformer condition monitoring (OilQSens)

The combination of advanced diagnostics for the analysis and the online oil conditioning systems have enabled us to assist our clients in:-

  • reducing the risk of failure in transformer fleet
  • optimising maintenance 
  • extending asset life
