Abstract :
High voltage insulation systems require voltage stress grading for proper operation. Silicon carbide is a semi-conductive compound with non-linear voltage current characteristics that is commonly used in the form of paints and tapes for the basis of voltage grading systems. This paper reviews the basic requirements of the stress grading system in generators and how the non-linear characteristics of silicon carbide are utilized
