In this paper, the finite element analysis software comsol is used to design two different defect models on the short-string composite insulator model, namely, the air gap defect and the mandrel-damp defect. The thermal field of composite insulators with two kinds of defects is simulated, and comparing the axial temperature gradient changes of mand-sheath interface under normal condition and under the condition of defects. The results show that local heating does not occur when the composite insulator contains an air gap defect without partial discharge.
