A basic study of the aging process in solid dielectric cables, Part 1
The Department of Energy, Electrical Energy Systems Division, has initiated a 4-year study concerned with the aging of extruded power transmission cables. The program has two principal objectives: (1) develop a basic understanding of the physical mechanisms of dielectric aging and failures, and (2) develop a nondestructive, accelerated test for predicting the service life of these cables. The program is devoted exclusively to the most widely used solid dielectrics, viz. low density polyethylene, cross-linked polyethylene, and ethylene propylene rubber. For purposes of this program, it is assumed that the cable will be isolated from the external environment during service. The program consists of four sequential tasks, the first two of which are completed. The results of these first two tasks are described in this report. The report also contains an overview of preliminary plans for the third task, a comprehensive experimental program.
