  • Abstract
    Carbon oxides are produced from the degradation of solid insulation in oilfilled equipment and to a significant extent, especially carbon monoxide, from the insulating liquid itself. For mineral insulating oils, carbon monoxide is a reliable indicator of low or moderate thermal stress, and for natural esters, ethane is an indicator of the oxidation stability of the insulating fluid.
