A power utility company want to install two on-line DGA monitors for their transformers. It will be greatly appreciated if anybody here like to recommend some available products or the exprience with using them to me.

please take a look at the post and give any suggestion

RE: On-line DGA commercial products recommendation

I have recently installed a Morgan-Shaffer Calisto, which is a new hydrogen and water monitor.  It is not a full on-line DGA, by is similar to the Hydran or other units.  The Calisto was easy to install, program and provides very accurate data.  I would recommend this for hydrogen and water monitoring.  Sudden increases in hydrogen are predictors of transformer failures.
