This final project of master’s degree investigates combined insulation parameters characteristics of electrical equipment. The purpose of this research is to evaluate defects parameters characteristics in the insulating pressboard, while changing oil level in insulation model. The investigation describes the experimental test that analyses characteristics of parameters of insulating pressboard and insulating pressboard dipped in oil, while testing it with 11 kV voltage. The mathematical model was adapted to investigate characteristics of partial discharge parameters using combined insulation when insulations defect is in the solid insulation, stating that the oil is free from defects. Mathematical model shows characteristics of parameters, when changing the size of defect and the level of oil insulation. Investigation revealed the dependence of characteristics and the critical size of defects in different level of oil in the insulation model. Method for determination of electrical equipment insulation condition was presented. |
