Questions pertaining to Transformer DGA and Duval Triangle

  1. Nov 17, 2014 #1
    Is anyone versed enough in Power transformer DGA and Duval triangles to know what the implications of the different regions might be? I've Googled and found many documents about the subject, but none really seem to mention what the implications might be for a transformer that tends towards T3 as apposed to T2 or T1; or what may cause a transformer to experience partial discharge. There are, of course, explanations of what these regions are, but no real in depth discussion of what they mean so far as transformer health.

    Any help would be obliged.

    Thank you. I'll have to wait to view it on my home machine; it seems there's some type of firewall preventing me from seeing the link.
