Identification of Stray Gassing of Inhibited and Uninhibited Mineral Oils in Transformers
Michel Duval, Thomas Heizmann
March 28, 2023
The aim and contribution of this paper is to identify with Duval Pentagon 2 the stray gassing (SG) patterns of inhibited and uninhibited mineral oils in transformers in service and in the well-established laboratory SG tests of CIGRE and ASTM, so that SG in transformers can be easily distinguished from the other types of faults occurring in them. The SG test of IEC 60296-2020 is inadequate or much less effective for that purpose.
