Precision and Performance Evaluation of Accelerated Aging System for DC TP Power Cables

The demand and necessity of direct current (DC) has been increasing owing to large capacity long distance power transmission. DC application TP (thermal plastic) materials, which can increase the transmission compared existing insulation primary focus studies. This study presents development a highly reliable accelerated aging system that implement conditions cables. Moreover, we verify its reliability by testing model cables analyzing characteristics. Accordingly, developed an simulate thermal, electrical, mechanical stresses collectively. We used perform test cable for 40 cycles. control precision during was numerically calculated. evaluated using conduction chemical characteristics aged experimental results show is 1 % cycle. increased more than 100% before aging, thereby it verified performance accelerates It expected be long-term tests as diagnostic technology
