Abstract To avoid insulation deterioration caused by partial discharge (PD) in air gap defects of medium voltage cable terminations, a new method of suppressing PD was presented by filling nano-TiO₂ composite coatings into the defects. The influence on insulation was investigated by analyzing PD characteristics and surface morphology of the defect. The defects were designed and the electrical-thermal aging experiments were performed in a 10kV termination. PD characteristics and surface morphology were analyzed. Moreover, the finite element model of the defect was established to discuss the impact mechanism of the composite coatings to PD and surface morphology. The results show that PD energy reduces significantly after filling the composite coatings, and the discharge repetition rate and phase distribution difference are not obvious with the increasing of aging time. In addition, the surface of the defect is smooth and carbon content of the agglomerated particles decreases by 31%. It is also indicated that nano-TiO₂ composite coatings can suppress PD development and retard insulation deterioration.

Key words： Cable termination air gap defect partial discharge composite coating discharge energy
