TL;DR: In this paper, high amounts of dibenzyl-disulfide (DBDS) were found in many of the tested oils, which may cause shorting faults between turns.

TL;DR: In this paper, the nature and causes of corrosive sulfur induced failures in oil-filled transformers and shunt reactors are examined in the presence of paper tapes insulating the conductors.

TL;DR: In this paper, the behavior of corrosive sulfur in mineral oils is examined in terms of the failures observed in transformers, the surfaces of the copper sulfide covered conductors and degraded paper insulating tapes.

TL;DR: The average elapsed time from the incipient formation for the cavity to the onset of the first partial discharge event extended downwards from 0.62 to 0.42 /spl mu/s with increasing oil viscosity as discussed by the authors.

TL;DR: Partial discharge pulse phase analysis carried out on a mineral oil and a perfluoropolyether with point-to-plane electrodes provided further and additional evidence that discharge epochs tend to be concentrated in the vicinity of the alternating voltage peaks at discharge inception in lieu of the voltage zeros characteristic of normal cavities occluded in solid and liquid-impregnated solid insulating systems as mentioned in this paper.
