摘要：

Transformer oils were analyzed at different service times by IR spectrometry and by a kinetic method using a model reaction of initiated cumene oxidation. The concentrations of an antioxidant additive (ionol) and the degrees of formation of new oxidation inhibitors in transformer oils can be differentially quantified with the use of the two techniques.
