Abstract :
The effects of space charge on insulating properties of modified epoxy resin system DGEBA/MDA/SN was studied by using DSC and TSC. Three characteristic TSC peaks in the temperature range from -150 to 250°C, consisting of a β peak at 162.1°C and γ and δ below zero, were observed. Tp moved towards lower temperature with increasing SN contents. Space charge accumulated and impurities changes the initiates the electrical treeing
