Abstract:

A review and an interpretation of the existing literature on dielectrics and dielectric breakdown was completed. Experiments were planned in light of the above interpretation and an experimental system was designed and developed. Experiments were then conducted on the time-to-break and breakdown of composite laminate insulation structures under pulsed and alernating voltages. Corona inception and extinction signatures were simultaneously obtained and evaluated. In view of the future experiments planned, theoretical and computer studies were carried out to determine the rise in temperature of laminate insulation structures under pulsed loads, Keywords include Field, Electrical Insulation, Pulse Voltage, Corona-Interception, Corona-Extinction, Partial Discharge, Breakdown Temperature Rise.
