Abstract :
The features of the discharge development and the breakdown of insulation models with two insulation barriers and three oil gaps have been investigated. The main parameters of predischarge channels under full and partial breakdown of models are determined, the correlation between them and between the relationship of the breakdown voltage of oil gaps of models is established
