Abstract

This paper describes sheath induced voltage and operating characteristic of cable cover protection unit(CCPU) in underground transmission cable. Real cable system operating by 154kV XLPE cable was modelled for simulation. Sheath induced voltage and operating characteristic of CCPU were analyzed. In particular, sheath induced voltage was analyzed in case of individual grounding and common grounding, respectively, and operating characteristics of CCPU were compared each other.
